Title: [lib] libgbpak - a Transfer Pak beta library and dumping-tool v0.63.2
Post by: saturnu on April 14, 2014, 03:59 PM
(https://my.mixtape.moe/xqqxwt.png)

Hi,
here is my transfer pak source and demonstration program :D

EDIT 1: bugifx - something important was commented out ^^
EDIT 2: v0.2 ram reading/writing
EDIT 3: demo tool update
EDIT 4: demo tool bugfix on newer os
EDIT 5: v0.62 MBC2 RAM dump fix
EDIT 6: v0.63 tv_mode force off - some experimental stuff

if you want to try out the lib, it seems that this tool is "save" to use anyway. :D

WARNING: this isn't tested on any retail cart until now.

keep in mind that the transfer pak isn't a flagship in engineering at all.
better clean the contacts, don't shake it to much and make a test-dump before writing to it. ^^
i mean it should work. :D - just be careful ^^

i was a bit to lazy to program a proper file selection screen, so the restore function is
enabled in the menu, if a file is found that matches up the way the tool is doing it's backup.

e.g.
TITLE: THE GAME
FILE: /GB64/THEGAME.srm

gb64_latest_version (http://krikzz.com/forum/index.php?topic=2298.0)

(force tv type, if the picture is running wild)

good luck! :3

I got it to work and was able to repeat it one or two more times. I have everdrive64 v2. Here are the steps I took:

1. System was turned off
2. Plugged both gb camera and transfer pack SNUGGLY into the controller on port 1.
3. Turn on and start  libgbpak beta v.6 (with sram write)
4. Libgbpak makes the gb ding sound and shows the "check connection" message on the bottom and NO -1 or -4
5. If requirements in step 4 has been met, then slightly pull the gb camera out JUST A LITTLE BIT instead of it being all the way in the transfer pack. I am talking about 1 or 2 mm.
6. Press the reset button on the system - not powering it off.
7. Start libgbpak again with a little prayer...
8. Once it shows the name of the game, press B to dump the SRAM, and be patient because it is about 128KB.

Can this information be added to the main post or the readme file or something? I was having the same issue, and pulling the cartridge out just a tiny bit really did the trick.

I don't understand what this is. Is it so you could upload like your game save from Pokemon gameboy to pokemon stadium?
Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: saturnu on April 14, 2014, 07:02 PM
basically it's library, so developers could use of the transfer pak.

the transfer pak can:
- read rom
- read ram
- write ram
(- read/set rtc - activate rumble)

atm. it could only read the rom, but not the ram (savegame)

this would be a pokemon stadium romhacking job, 'cause it's the only good emulator out there.
gnuboy64 has some sound issues and gblator has no sound at all. ^^

i think a cool features could be the possibility to transfer savegames from your original carts to the edgb or sdcard. :>
or maybe a savegame cheat tool which allows you to search for and alter some values inside the savegame.

atm. i have a modified version of my menu with a modified version of my loader64 to transfer the romdata from sdram to the pc.

i would be grateful if someone would help testing. ^^
i'm planing to realease some tools you could play with, but today my sd2snes has arrived so this will have to wait. :D
Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: saturnu on April 20, 2014, 11:28 PM
on the top left is my usb loader client in the terminal, dumping the ed64 sdram.
the ed64 is running alt64.
on the right you can see geany with the the library source. ^^
it's great that it's possible to use the ed64 sdram as extended ram, 'cause the n64 only has 4 or 8Mbyte rdram. :>

Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: saturnu on April 22, 2014, 03:58 AM
hi,
perhaps someone could test this for me?
i'm unsure if there is a timing error in my disk saving or if it's just caused by my new micro sdcard.
most of the time the files are ending up in 0-byte but sometimes it's working. ^^
the dumping is allright, i could print out the correct bytes... it's just an saving error, somehow. -_-


install: copy the GB64 folder to the root of the sdcard.
(warning: writes to the false sectors) :>


usage:
insert the transfer pak and the rom before starting the rom.
if you could read the title push 'A' to dump.

Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: Paulweeze on April 22, 2014, 05:26 AM
Im gonna test it out for ya with a few different titles :D. What do the error messages corespond to? I assume that -4 means no transfer pack and -1 means no rom?
Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: Paulweeze on April 22, 2014, 05:53 AM
I got it to show up with a name (had to use a different controller) and dumped it but I can't find the dump. Where does the program dump the rom to? Btw, does this require a microsd card?
Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: saturnu on April 22, 2014, 11:58 AM
no ^^ it doesn't require a microsd card.
the errors mainly mean, that the connector is dirty :>
the file should be in '/GB64/romtitle.gb' and hopefully has some bytes in it?

EDIT: found another sdcard in my camera, it looks like the sdcard isn't the problem. :/

hm,
the whole system freezes right after
diskWrite(begin_sector, (void *)0xb2000000, file_sectors);
even with the non-dma
fatWriteFile(&rom_data, gbcart.romsize/ 512);
it hangs :D

it's working randomly, so it can't be completely wrong this way. ^^

the dumping isn't the problem, i can readout the data with usb just fine :D
Title: Re: [lib] libgbpak - a Transfer Pak beta library
Post by: saturnu on April 22, 2014, 04:51 PM
Hi,
the save bug is fixed!
here is the first working preview rom. i've still disabled ram dumping, 'cause of security reasons. ^^
i don't want to mess with your savegames, without testing it by myself before. :D
the rom is saved under the '/GB64' directory and named after the title.
if you want to give me some feedback/bugreport, please copy the information from the info screen, too. :>

install: copy the GB64 folder to the root of the sdcard.

Okay, I dumped both the save games and the roms of Super Mario Land 2 (GB) and Zelda Oracle Of Seasons (GBC).  Here's what I found:

- SML2 dumped perfectly.

- The file Zelda created worked, however it was dumped as ".gb", not ".gbc".  Absolutely not a big deal, just thought I'd let you know.

- Both save game files were dumped as ".srm".  I had to change them to ".sav" in order for VBA to detect them, but they both worked perfect!

- I tried the original cartridges on my GBA and using your software did not correct the save files: The cartridges still worked perfectly.

So far, it looks great!  I only have one suggestion:  Instead of having it say "power off" after it's done, could you have it go back to the main screen?  Maybe have it say "Hit A to go back", or something like that? 

Thanks for the great work!

i'm totally amazed that it's working. :D
but not every savegame is the same, some are bigger, some are smaller and using other memory bank controllers. ^^
appending a 'c' to the file extension is fixed in minute. ^^
btw. the 'power off' is just a note, 'cause the previous 'Z - Exit' didn't work after writing to the sdcard. :D

Tested with Pokemon TCG. The ROM dump loads fine in bgb and Everdrive GB, but the save dump doesn't load in either bgb or on the Everdrive GB.
Dumped SAV again, and works fine now.  :o
Super Mario Land 2 ROM and SAV dumps work fine.
Legend of Zelda DX ROM and SAV dumps work fine.
Title: Re: [lib] libgbpak - a Transfer Pak beta library v0.2
Post by: saturnu on May 10, 2014, 06:41 PM
thanks for the report.
it seems like a good idea to compare a few dump results in a next version of this tool, so it could alert the user, if there is a bad connection.
Title: Re: [lib] libgbpak - a Transfer Pak beta library v0.2
Post by: adimifus on May 10, 2014, 07:03 PM
It's weird. I looked at the first save dump I made in a hex editor, and there was a lot of text data that pertained to the game (namely deck names) but i guess it was corrupt enough to not be recognized by the game. All subsequent dumps I've made worked fine the first time, both for ROMs and save data. Maybe the dump compare thing could be an option?

One strange thing that happened was I accidentally dumped a game twice in a row, and somehow a duplicate file was created with the same file name. It doesn't show up when I look at the ad card on my computer, but it's still listed in the everdrive menu. And if i view the file using the everdrive, there is data like the file is actually there. (maybe it is? But why can't I see it on my pc?)
Title: Re: [lib] libgbpak - a Transfer Pak beta library v0.2
Post by: Paulweeze on May 10, 2014, 07:37 PM
Thats weird. When the file duplicates itself, you can generally see it in your computer. When you go to delete both, it doesn't actually get rid of it until you leave the folder and go back (at least in windows). Btw, i found out that the multicarts i dumped retain the game that the header is named after (and have a different checksum). For example, for the 37 in 1 if you choose pacman sce, you can play it. Anything else softlocks an emulator. And I finally got a pokemon save to save  ;). Had to rename it .sav for visualboy advance but at least I can set these saves aside for when I get a edgb. I appreciate your hard work Saturnu!
Title: Re: [lib] libgbpak - a Transfer Pak beta library v0.2
Post by: saturnu on May 10, 2014, 11:16 PM
hm yes, there needs to be additional checks, if a file already exists.

in windows or dos there couldn't be more than one file with the same name in the same folder. ^^
in linux it's case sensitive so it's somehow possible (for the os "test.dat" and "Test.dat" are two different files).
now guess what's going on with the everdrive os? if you are not careful enough you could add more then one file with exactly the same
name in the same folder. :>
you could delete that duplicate with linux and windows chkdisk could fix that problem for you, too.

but this shouldn't be a problem for the user, it's something a programmer should take care of instead. ^^
Title: Re: [lib] libgbpak - a Transfer Pak beta library v0.2
Post by: adimifus on May 10, 2014, 11:42 PM
The duplicate ONLY showed up in the everdrive OS. And the filenames were exactly the same, including case. Only one of them showed up in linux for me (not sure what it would look like in windows). What's really odd is I did the same thing once before (tried to dump the ROM when I already did) and it told me the file already existed. So I don't know what happened to cause the duplicate.

the only games that are fully working right now are:
mickey's speedway usa
mario golf

i still have to test:
mario tennis
perfekt dark

No need to test, just dump your save for your own purpose :D. Saturnu's program has allowed me to dump about 5 or so sram saves that work with the EDGB, a bunch of my own games, and multicarts. I wonder if it would work with eeprom prototypes though?

Thanks. Works like a charm. ;D
Dumped my yellow, gold, silver and crystal saves without problems.
Is it possible to restore save files to the cartridge back?
Didn't find a option in the application.

Just registered to thank you for this amazing tool! :)

I tested it yesterday with 5 games. All of them dumped successfully, same goes for the savegames.
Next thing I tried, booting up a GB-Emulator and load up my fresh dumped games with the according savegames.
The .srm files simply renamed to .sav, the Emulator recognized these and everything worked fine.
The last thing I did was grabbing a savegame from the web for a game, renamed it according to my own dump and then write it to my GB-SRAM. Worked nicely as well, now I have a third party savegame on my cart.

Just had a weird issue with a modified Pokemon Crystal save. The restore worked fine in general, but Pokemon Stadium 2 froze once I clicked on the edition in any menu. After a reboot, the savegame was wiped again. Guess this is related to the savegame after all.

Anyway, once again thank you very much for this useful tool!

Post by: saturnu on December 22, 2014, 03:47 PM
hm yes, i looked at the camera rom header and it's using a special mapper (0xFC), that is capable to do the camera stuff beside the rom/ram mapping.
a pretty logical implementation, to say the truth. ^^

atm. i don't own such a camera and it's pretty awful to program for a device, totally blind. :D

camera support? on the next fleamarket, i'm looking around for one. i don't think it's worth it - sending one around the globe. :>

btw. i thought about a microcontroller based transfer pak emulator, something like a flashcart, that could be connected instead of a joypad or as an adapter. :>

it's more or less just a copy&paste job. i have the controller code and transfer pak code ready, but atm. i'm not sure about the interface.
maybe just sram and a homebrew on the ed64 uploading to the device, or a seperate sdcard and some buttons.
there are pros and cons...

but atm it's on the bottom of the todo list, i have to finish other projects first. ^^
hopefully someone is faster than me, after reading this. :D

- gameboy camera sram dump support (untested) - tested by gojira54, should work

I'm not sure if the camera sram dumping works ^^
would be cool if someone could give me a feedback on this

writeback of the camera sram is disabled, 'cause i don't have a camera and couldn't test if it's working. (don't want to currupt your data) ^^
(maybe it's already working. if someone really needs this feature, leave a comment ^^)

Post by: Mattroid on April 05, 2015, 10:17 PM
I'd like to help test camera compatibility, but I can't get it to recognize the camera. I tested with a GBC game and everything there seems to work fine, but the camera continues to give a "check connection" message. First time it gave me error -4, I then cleaned the contacts on the camera. After that, it gave me error -1. Since then, it doesn't give me an error code at all, but has always simply said 'check connection' at the bottom.

So I'm not sure what's up with that. Anything else you can think of that I might try?
Title: Re: [lib] libgbpak - a Transfer Pak beta library and demo-tool v0.6
Post by: saturnu on April 05, 2015, 11:02 PM
hm this is strange, what version are you using?

Code: [Select]
if(_set_gbPower(0)!=0)
return -1;
   
//get power status 0=off 1=on
if(_get_gbPower()!=0)
return -2;

//set power off 0=off 1=on
if(_set_gbPower(1)!=0)
return -3;

//get power status 0=off 1=on
if(_get_gbPower()!=1)
return -4;


this is happening after starting the tool:

1. turn off power -> if it fails: error -1
2. check if power is off -> if it fails: error -2
3. turn on power -> if it fails: error -3
4. check if power is on -> if it fails: error -4

in your case:
first it could not check for power on
than it could not set the power off?
and than nothing?


- you have to power off the n64
- insert pak and cartridge
- than start the n64 and the tool

if you change or reinsert the cartridge, it's not enough to just reset the n64 or to go back to menu and start the tool over again

some guy already dumped his camera with the tool and it's more or less doing the same with the camera as with the normal cartridges :>
so i can't say that there is anything special you could try beside cleaning.

I tried both v0.5 and v0.6 (w/ram write), though with v0.6 I may not have shut down the N64 after testing the GBC game. I'll go try the camera from boot up now and report back.

EDIT: Same problem. Weird. I'll take the camera apart and clean it better when I can...I can't seem to find my triwing or technical screwdriver set so I'm kinda stuck at the moment.

Post by: saturnu on April 07, 2015, 01:07 AM
i'm not sure what's happening if all the power commands are failing.
maybe the 3v3 power supply rail is a bit weak after all these years.

in my case i have some ripples on the 3v3 rail as well.
this could be fixed by recaping the power supply. :>
(it's making funny noises even with just the few mA more, the expansion pak needs, if i insert it ^^)

every device you add uses a few mA more and stresses the power supply

if you have some problems with the tool:
maybe it could help to replace the expansion pak with the jumper pak
or unpluging all other joypads...

the 3v3 rail starts at the power supply and goes
[power supply 3v3]->[n64]->[joypad]->[transfer pak (3v3->5v)]->[cartridge]

these are quit a few connectors and
if you want to try to reduce the impedance by cleaning them
these are the important points

isopropyl alcohol and a gum eraser are good tools for it

n64 side of the power supply connector
(http://abload.de/img/power_n64_sideg8u74.png)

n64 side of the joypad connector
(http://abload.de/img/controller_n64_sidekdun4.png)

these are the more critical ones
even shaking the pak while using it could produce errors

as you can see gnd and 3v3 are split over a few pins

front of the pak pcb

back of the pak pcb
(http://abload.de/img/pak_header_backmfur9.png)

game boy carts, are transported in pockets, lying on the carpet...
there is a good chance for dust to cover the contacts and even to go over into the cartslot

for the cartslot on the tp, maybe you could use some cardboard ^^

(sandpaper isn't a good idea, think of corrosion ^^)

keep up the great work! i was so happy to find this program a few months back, as well as your write up for transfer pak with everdrive GB. in another thread about the GB camera, you mention maybe adding support for changing to port 2. I don't know how hard this would be, but i would love it for my handheld 64, as i like to use the second port for transfer pak.

Yeah, I got two transfer packs from ebay yesterday and immediately tried to back up my gameboy camera... I had the same check connection and -1 and -4 errors as the above posters.

I cleaned the connectors on the transfer packs with alcohol and normal gameboy games would immediately just work and get recognized. I was able to dump as well, but gameboy camera would never show up. Turning on and off would not get the camera to be recognized.

Perhaps like you said, maybe the power supply is dying. I will look into getting a 3rd party power adapter and try again.

Edit - Updated 1:51PM 5/27/2015-
I got it to work and was able to repeat it one or two more times. I have everdrive64 v2. Here are the steps I took:

1. System was turned off
2. Plugged both gb camera and transfer pack SNUGGLY into the controller on port 1.
3. Turn on and start  libgbpak beta v.6 (with sram write)
4. Libgbpak makes the gb ding sound and shows the "check connection" message on the bottom and NO -1 or -4
5. If requirements in step 4 has been met, then slightly pull the gb camera out JUST A LITTLE BIT instead of it being all the way in the transfer pack. I am talking about 1 or 2 mm.
6. Press the reset button on the system - not powering it off.
7. Start libgbpak again with a little prayer...
8. Once it shows the name of the game, press B to dump the SRAM, and be patient because it is about 128KB.

Thank you Saturnu for creating this awesome tool!

Hey!

I've also now had success. I cleaned the camera pins again, plugged it all the way in, then tried the reset thing and it worked after a couple of tries.

I didn't have to do the pulling out slightly thing. I also used the version which apparently had the write function disabled to put my Pokemon save onto a cart, or was it only the camera that was locked out from doing that?

Can you add support for dumping unadvertised sram?

I try to back up my Final Fantasy Legend 1 (aka Sa-Ga) game since it only has 1 save file. But I never could with Mega Memory Card or Monster Brain.

I try GB64 and it says the game has no sram! So I think it is a mistake in the rom header.

I think Final Fantasy Adventure (Seiken Densetsu) has same problem.

It is Ok to overdump the unadvertised sram I can fix it.

Thank you for this program.

ah, thanks for that info.

it was just a tiny bug in the interface, cause the save option was only enabled, if there is external ram available.
the mbc2 has internal ram, so only the battery flag was set and not the external ram flag.

i don't know if it's working properly, i haven't tested it by now. ^^

Thanks but I am having two problems with 0.62.

1 is, it seems to be stuck in PAL mode? My screen rolls like crazy and I can barely see what is on the screen.

2 is, I tried to dump the sram but it created a zero byte file SAGA.SRM. I can't read the screen to see if there is any more info to report. I dumped a pokemon game with 0.3 and got a 32k srm file.

Any chance you can fix the screen mode thing? It's hard to dump when you can't see the screen properly O_O The 0.3 version displays fine for me.

0.61 also goes to PAL, that's oldest version I have other than 0.3.

Latest version of 0.63 fixes the screen problems thank you! :D

One last request, and this may be too much work / too difficult, so it is fine if say no, please don't worry about it! :)

Can you figure out how to dump saved games from Mega Memory Card by InterAct? I've got a few carts with dead batteries so I can't restore saves from MMC in order to dump them with ed64. I guess I can figure out how to change the cart battery evenutally tho..

I dumped MMC rom and I can see the save game file table at 0x7800 with my save file titles listed and if I run the DEMO.GB rom in an emulator it show my games in the delete menu like normal. So if we're lucky getting at the saves might be as simple as overdumping DEMO.GB?

Anyway I'm very happy with this program as is already thanks so much!!! :D :D :D


edit:

Here is a picture (http://www.pcworld.com/product/pg/271342/detail) of MMC.

Also it seems all of 0x7000 ~ 0x7FFF is used for file management. I see this by comparing with
 never used MMC rom  (https://www.loveroms.com/download/gameboy/megamemory-v10-by-interact-e/66846)file from the net.

0x7000 ~0x7800 looks like a FAT table!

basically i know nothing about this devices memory mapping and i don't have one to experiment with.
if you want to overdump a mbc5 rom or something, i can provide a testversion, that doesn't use the information from the romheader for the rom/ram size.

the linked DEMO.gb is set to -> mbc5 + 32KByte ROM + 32KByte RAM

Here is a hardcoded libgbpak version that is using 4MByte ROM + 128KByte RAM
https://f.zdev.com/dl/stqysj.z64

keep in mind, that this is taking ages to dump. ^^

Title: Re: [lib] libgbpak - a Transfer Pak beta library and demo-tool v0.62
Post by: timmy on February 10, 2016, 01:12 AM
That header might be inaccurate. It's unlicensed cart so it may not use a MBC series chip. It definitely doesn't have a battery. It might have extra ram but I can't think why it would need it unless GB ram isn't enough to hold the file table + buffers. I can see 4 ICs inside but I can't tell what they are. Three have pins on all four sides and one has two rows of pins. Probably at least 1 is EEPROM/FLASH chip.

I tried the overdumper version but the resulting rom was repeating the part from 0x4000 ~ 8000 over and over again. SRAM was just FF entirely. I guess the only way to get at the game files is for someone else to reverse the code and figure out the memory map.

Thanks anyway! It was a good try! :D

Post by: saturnu on February 10, 2016, 08:36 AM
yes, this makes sense. ^^
but i somehow hesitate to monitor the register access with the rom that's online. maybe it's a dead end to experiment with that rom at all, 'cause nobody knows if it's a clean dump. ^^

Not sure if this could help on implementing HuC3 (this game probably has little documentation),  but 'Robot Ponkottsu 64 - 7tsu no Umi no Caramel (Japan)' is an N64 title which used the transferpak to receive data from the japanese Robopon GBC titles, Sun/Star/Moon. (These games have custom cartridges with speakers + a replaceable cr2025 compartment, and use HuC3.)

is it possible to use libgbpak with this concept --> (http://micro-64.com/features/gsneon64.shtml) (homebrew uploading to the n64 via gameshark), to run this program on a real N64 console without needed an everdrive? does the program need to be modified?

libgbpak is a library, that you can use in any of your c64 programs, the demonstration tool is everdrive specific.
so in theory it is possible to use the library in some homebrew with a gameshark, but you need to figure out a way to transfer the roms back to the pc.
maybe you can get use of the LPT port or the controller pak and a dexdrive. ^^

if you are going to program a gameshark version, say so. the library uploaded is a bit outdated, so i need to update it, if there is a serious homebrew project incoming. ^^


EDIT:
i guess the lpt port might be possible with a gameshark pro.
-> dump the rom to the rdram -> dump the rdram with the gameshark -> use some extraction tool - to dump the rom out of the ram image

I know this method found here (http://www.paulscode.com/forum/index.php?topic=810.0) and here (http://www.nesworld.com/article.php?system=n64&data=n64-howtodumproms) will connect the gameshark to the pc and you use "Game Software Code Creator" to extract the file.

The way i saw it was do this same setup, but instead of loading the neon64 homebrew, loading the demonstration tool homebrew for the everdrive. which could be used with "Game Software Code Creator" to extract files from the transfer pak to the pc. It's just since the everdrive version runs right to an SD card, if i ran it on a gameshark, there would be errors.

I didn't know if the library was already configured for gameshark. I didn't want to mess up a sm64 cart! :)

edit:
A more visual way of explaining process tree i was going for:
1) use this method (http://micro-64.com/features/gsneon64.shtml) but instead of loading neon64, load the everdrive transfer pak demo
2) plug game into transfer pak on controller with game
3) use that program to save instead of to SD card, but to ram of gameshark/n64
4) program on PC freezes to give you a chance to press button on Game Software Code Creator
5) file loads to pc
6) loops back to title screen of program

i just didn't know if this library treads the SD card of the everdrive as any storage device on the hardware (including ram)

Hey Saturnus,

Just got my Everdrive V3 a few hours ago,

Been having an issue getting PKMN Crystal Cart to dumb onto my SD card.
When i get to either dumping RAM, or Dumping ROM, I get an message "File Already Exists on Drive"

Especially after trying to do a RAM dump it advises me to "Power Down" and after hitting Z, the text gets loaded up and distorted.

In addition the Screen Is not loading the background for the Rom when loaded up off of the Root menu of the SD drive.

I have the most updated version of the OS for the Everdrive, and the most updated version of libgbpak.
The Carts are all ntsc including Everdrive Cart at the moment

I couldn't find anything that this is exclusively working for only PAL carts at this time, is this the case?

I have a 2.5 and am getting the same problem (black background, file already exists).

Clearly the application is having trouble reading the SD card, especially since the background is black..

bugfix version released v0.6.3.1

- v2, v2.5, v3 compatibility fix
- additional PAL 256x240 interface for better compatibilty
- startup 'bing' sound removed

if you are using a v1 you should try the legacy version v0.6.3

Well... it almost works. Whenever I dump either the save or the ROM, it fails very consistently. I'm trying to dump Pokemon Red for starters, and the application reads it correctly (so does Pokemon Stadium), but when I dump it, it outputs a file that has two repeating hex values instead of what's supposed to be there.

Ex: "POKEMONRED " becomes "POPOMOMORERE"

I thought it was just a bad connection, but I cleaned everything like crazy and it's still not working, even though everything works perfectly in Pokemon Stadium.

On an unrelated note, is there a chance of applying this fix to alt64 so I can use that on my ED64 2.5?

Hey saturnu i have a question. can your program be updated to dump a gameboy test cart?  im at the end of my rope trying to find a way to dump this cart. and i see your still activity working on this program?

It recognizes there's a cart in the slot (with the name DMG AGING)  but it shows check connection so i cant dump it.  and yes the connection on the transfer pak controller and cartridge has been polished to a shine and the slots are clean. so i know theres no bad connection.  ive tried 3 other transfer paks and controllers with version v0.6.3 and v0.3.  it works with a regular cart.  its important i get this dumped cause its an eprom and eprom data will die from bit rot eventually making this 1000 dollar cart worthless.  the cart works fine on every hardware for the gb gbc and gba.

here a scan on the cart disasembled. it uses a full size 32k eprom

hm yes,
the dump fails 'cause i check for a good connection by the cartridge name in the header.
it seems like in this case it starts with a blank (0x20), i guess i should improve this anyway. ^^

I hope so cause the next step is to de solder the eprom from the board, buy a programmer and dump it that way.  The retrode doesnt work corectly with this cart so im out of options.  If im correct this rom doesnt have header data but im not sure.

Let me know if you can come up with something :P  Thanks!

I just wanted to pop in and say thank you saturnu.  I haven't tested the new version, but back when I first picked up my ed64 the first thing I did was back up my old GB/GBC saves.  It's a good feeling to have all of those old memories somewhere safe :)

Dang well i thought maybe it was because it was on fat32 so i switched to a 2gb fat formatted card and didnt get any different results.  so should i try a earlier OS or everdrive?  or doesnt it just not work with v2.5/v3?

I'm testing with the latest OS v2.12 on my ED64v2.0 and iwasaperson is using a ED64v2.5.
Acutually i don't know what's going on with your cart.
you can try put it on an alternate sdcard and place it as OS64.v64 in the ED64 folder, to boot from it directly. ^^
Or you can try to backup your sdcard, format it with fat32 and use a 4KB cluster size.

changelog:
v0.6.3.3
- updated v2.5 fw

Oh!!!... I feel stupid now... i should have just read the dang readme file XD

"put the GB64 directory at the root of the sd card"
 now its working! derp...

And from what i can tell ive successfully dumped the rom! thanks man your a real life saver!

now i just got one more cart to dump and thats the n64 test cart.

Not sure if this could help on implementing HuC3 (this game probably has little documentation),  but 'Robot Ponkottsu 64 - 7tsu no Umi no Caramel (Japan)' is an N64 title which used the transferpak to receive data from the japanese Robopon GBC titles, Sun/Star/Moon. (These games have custom cartridges with speakers + a replaceable cr2025 compartment, and use HuC3.)

https://github.com/Drenn1/GameYob/issues/51#issuecomment-16026325

Phenomenal work so far by the by, very impressed at the support for custom carts like pokemon rumble pinball and the gameboy camera  :)

Just wanna add onto this, there's an open source GB emu called "GEST" made specifically for the obscure HuC3 mapper. This was the only emu I've seen that can read/write battery files for HuC3 games like Robopon.

I built a standalone GB cart reader with support for all of the official mappers.

I dump HuC1(0xFF) as MBC1 and HuC3(0xFE) as MBC5.

MBC7(0x22) and TAMA5(0xFD) are the problem carts when it comes to save games.  MBC7 uses reads/writes to 0xA080(Kirby)/0xA180(CMaster) and TAMA5 uses 0xA000/0xA001 for both ROM and RAM.

Latest version of 0.63 fixes the screen problems thank you! :D

One last request, and this may be too much work / too difficult, so it is fine if say no, please don't worry about it! :)

Can you figure out how to dump saved games from Mega Memory Card by InterAct? I've got a few carts with dead batteries so I can't restore saves from MMC in order to dump them with ed64. I guess I can figure out how to change the cart battery evenutally tho..

I dumped MMC rom and I can see the save game file table at 0x7800 with my save file titles listed and if I run the DEMO.GB rom in an emulator it show my games in the delete menu like normal. So if we're lucky getting at the saves might be as simple as overdumping DEMO.GB?

Anyway I'm very happy with this program as is already thanks so much!!! :D :D :D


edit:

Here is a picture (http://www.pcworld.com/product/pg/271342/detail) of MMC.

Also it seems all of 0x7000 ~ 0x7FFF is used for file management. I see this by comparing with
 never used MMC rom  (https://www.loveroms.com/download/gameboy/megamemory-v10-by-interact-e/66846)file from the net.

0x7000 ~0x7800 looks like a FAT table!

(http://i68.tinypic.com/2elyw04.png)
(http://i67.tinypic.com/amw8qx.png)
Finally found some time to look at the Mega Memory.  I'm still working out all of the little details but the two tables that timmy posted are the mapping for each stored save game and the save title list.  Each byte in the mapping table represents 0x100 (256) bytes.

The save data is run length encoded and uses the 1st byte of each block as the RLE marker.  For example, if the save game block starts with 0x12 then that is the byte used for run length encoding.  You will most likely see a bunch of 0x12s repeating thru out the block.  Each 0x12 (except the 1st one) designates a run length encoded item consisting of 3 bytes.  Following the 0x12, the 2nd byte is the count and the 3rd byte is the byte that repeats.  If bytes don't repeat in the save then they're stored as is. 

The actual RLE marker byte changes based on the save data.  The Mega Memory selects a byte not used in the save game.  This prevents corruption of the save game due to the RLE.

More testing to do.

For anyone wanting to dump their MMC and extract their stored saves, more details posted here:  http://forums.nesdev.com/viewtopic.php?f=20&t=15181

I got it to work and was able to repeat it one or two more times. I have everdrive64 v2. Here are the steps I took:

1. System was turned off
2. Plugged both gb camera and transfer pack SNUGGLY into the controller on port 1.
3. Turn on and start  libgbpak beta v.6 (with sram write)
4. Libgbpak makes the gb ding sound and shows the "check connection" message on the bottom and NO -1 or -4
5. If requirements in step 4 has been met, then slightly pull the gb camera out JUST A LITTLE BIT instead of it being all the way in the transfer pack. I am talking about 1 or 2 mm.
6. Press the reset button on the system - not powering it off.
7. Start libgbpak again with a little prayer...
8. Once it shows the name of the game, press B to dump the SRAM, and be patient because it is about 128KB.

Can this information be added to the main post or the readme file or something? I was having the same issue, and pulling the cartridge out just a tiny bit really did the trick.

Any updates on a release for a save dumper with huc3 support?

The speaker and RTC in huc3 cartridges make the save battery die very fast; which is why the cartridges for huc3 games are designed for battery swapping (while the game is powered on so the save isn't lost.)

Sorry to post about this again but I don't wanna lose my saves if I forget to replace the batteries on time lol

Can't dump the save from Pokemon Crystal (JPN) version, the English versions of Yellow, Gold work fine. Thanks for developing this tool btw!

If I view the Japanese ROM in GB View it shows SRAM as "UNKNOWN" meanwhile the English version says 256 KBit (32 KBytes (4 banks of 8 Kbytes each)), if that's any help to know what the region difference could be.
