EverDrive GB / Re: How to save game progress on GB Everdrive
« on: May 31, 2015, 12:40 AM »
It seems to me that EDGB is not what OP was looking for but it's his own fault. You don't even need to do any sort of research to figure out that the device would not suit your needs. You should always inform yourself about tue product you're purchasing.

But enough with he finger pointing, let's be helpful instead. So here's my honest tip to OP:
- Sell your EDGB. It's obviously not what you wanted.
- get a PSP. They can be found considerably cheap these days you should even have some money to spare from selling your everdrive. I would personally recommend the 2000 or 1000 series (not the e1000 - also known as psp street) as later revisions (the 3000 in particular, not sure about the street) do suffer from an LCD with huge scanline issues. If you can't get one of the recommended ones, a 3000 will do just fine, though.
- update it to the latest firmware, install a cfw and run an emulator. Masterboy is probably the best GB emulator for the PSP.
- alternatively, you could also get a GBA flashcard and use goomba color to emulate GBC games on the GBA hardware, if you're looking for a more authentic feel. It wont be perfect but most games will run flawlessly. The EZFlash IV micro was released just this year and can be had for a very reasonable price (usually ~30€), supports microsdhc and is very easy to use. Or you could wait for EDGBA, but I actually doubt that'll happen, especially with the recent release of the EZFlash IV micro.

What game in particular are you trying to save progress on? EDGB only saves SRAM, there is no savestate support.

Actually no. At least for me, the edge of my GBC cart was in the way of the sd sticking out so I had to cut it like the original edgb shell.

EverDrive GB / Re: CLONE or LEGIT EVERDRIVE?
« on: May 20, 2015, 11:49 PM »
As someone who recently purchase a clone, let me tell you: don't. Do not ever do it. See this thread in particular: http://krikzz.com/forum/index.php?topic=3007.0

You're lucky if it works at all.

The only reason I ever took my chances with possibly receiving a fake everdrive was the fact that it was pretty much 50% the money of the original EDGB shipped from my country. I figured "what's the worst that can happen? I receive a clone that works exactly as the EDGB." - oh how wring I was. While I was able to get a massive partial refund for the broken, obvious clone, the device is still pretty useless as it will not work 90% of the time and I ended up getting a legit EDGB which just works (tm) 100% of the time.

Long story short:

DO. NOT. GET. A. CLONE. EVER!

EverDrive GB / Re: Is the EDGB limited to 32k SRAM by Hardware?
« on: May 17, 2015, 11:50 PM »
Thanks,

well, that's too bad but I guess SRAM >32k is not very common so asking for upgraded hardware to support that is not very reasonable.

But then again, my idea works, it just requires patience and care (and making copies of the pictures before transferring them) so its still nice to be able to save the precious memories from my old GB Camera with tools I have readily available.

EverDrive GB / Is the EDGB limited to 32k SRAM by Hardware?
« on: May 16, 2015, 01:02 AM »
Hello,

I am currently trying to find a way to backup photos from my old GB Camera to my PC. I figured I could use the EDGB to load the GB Camera ROM then use a second GB(C/A) and a Link cable to transfer over the photos from the GB Camera to the EDGB, then grab the savegame from the EDGB folder and drop it into a programm called GB Camera Dump.

I've actually managed to do that by setting the save RAM to YES manualy after l load the Camera ROM. However, the GB Camera has 128Kbyte (16x8kbyte) of SRAM, EDGB only allows us to allocate 32kbyte.

The result is that the Gameboy Camera ROM will not work correctly and sending photos over to the EDGB might send photos into nirvana instead of the actual SRAM. I've found that apparently the last 6 photos i transfer over are actually saved. I fell like this is somewhat risky, as we could potentially loose precious photos that we might not have saved anywhere else (see http://krikzz.com/forum/index.php?topic=2865.0 for an example), luckily I am doing my experiments on a secondary, non-vital GB Camera.

Now my question: is the 32Kbyte SRAM Limit an actual hardware limit (i.e. there's only 32kbyte of SRAM actually on the board) or if it is a software limit that was set because it was thought a bigger SRAM was not needed? If It's the latter, can we expect 128Kbyte SRAM Support in a future OS Update?

Regards

Sascha

EDIT: From the looks of it, there's actually a 1024Kbit RAM Chip attached to the board, which would equal the needed 128Kbyte. Is the chip solely used as SRAM or does it serve another purpose? I assume the EDGB OS itself uses part of that for keeping settings?

I've seen many blatantly obvious clones of everdrives but not something that remotely similar to the actual product. May I ask where you got this from (so others can avoid the experience that you went through)?

Yes, you may, i bought it on aliexpress. I do feel somewhat ashamed that I ever actually believed I would get an original everdrive from china and I have contacted the seller and negotiated a massive refund and keeping the faulty item (as shipping it back to china is a hassle and too expensive). Since it sometimes works i feel i can live with that as a secondary everdrive.

Nonetheless, the one I received from everdrive.de is fully working and original and I am quite happy with this device.

So here's what I've learned: If you want an original everdrive that is fully working, get one from the list of trusted sellers. Do not buy from china. Ever. Not even if the description looks legit and the photos are convincing. Chances are, you'll get a clone that's not working properly.

Having received my EDGB from everdrive.de today (took less than 24 hours, I'm impressed) I think I can say for certain that what I received the day before is a clone/fake card.

The case looks identical and - at first glance - so seem the boards. Upon closer inspection you can tell some minute and some glaring differences.

1. The LED of the genuine EDGB is red. The fake one is green.
2. The chips and IC are mostly the same except for the two 16 bit BUS transceivers. The EDGB uses Philips brand chips, the fake one Texas Instruments labeled LVTH16245A
3. The transistor next to the transceivers is mounted at a 90° difference and only has 3 legs compared to the EDGBs 5 legs.
4. On the left of the Altera FPGA the two caps (?) are vertically aligned, on the EDGB they are slightly offset.
5. Between the FPGA and the NOR flash the EDGB has an additional capacitor.
6. On the backside of the board the traces of the EDGB seem to be a lot thinner and the "bone-shaped" traces on the right hand side of the board have a smaller circumference.

If anyone is interested I can provide images of the two boards side by side using a better camera than the one on my tablet.

EDIT: additionally, the about page of the fake one will display SN:1000 (I guess that means serial number) and device info will show an ASM Date of 2.0.1980, ASM Time: 0:0:2 whereas the EDGB will display a different hexadecimal SN and device info will show an ASM Date and Time of 21.4.2015 and 14:11:38 respectively.

Sorry to bump this old topic but since the OP is still active and I just came across this tool, I thought I'd share it. This tool allegedly does exactly what the OP wants to try to accomplish but I can not say for sure since I have not tested it.

Thanks for the response, gonna have to try that once my link cable arrives, see if my idea works.

Regarding my other issue: I think I might have received a fake EDGB/clone. I have now ordered from everdrive.de and I'm gonna see if that works better. Is there some way I can verify the one I have now is real or fake/cloned? Attached are some pictures.

EverDrive GB / new EDGB - some woes
« on: May 11, 2015, 11:23 PM »
Hello folks,

In just received my everdrive GB today and I have been fiddling around with it since noon. At first it worked, then it seemed to be broken and after hours of trying to fix it, repeatedly switching and reformatting sdhc cards it seemingly returned back to life.

It took me another few hours of trial and error to re-break and re-fix it and I am now at a a point where I think I have figured out what part stops working exactly and how to fix it but I am still not able to reproduce it controllable at a 100% success rate so i'll just start of with the first issue.

But before that, my setup: I am trying to use the EDGB on my GBA SP AGS-001 and a regular AGB-001 model. The micro SDHCs I tried are a SanDisk 2GB and an off-brand 8GB model. Both have been verified with a tool called h2testw which confirmed they are properly working and actually hold as much data as they claim they do (so no fake Chinese cards that wont actually hold the amount it says on the box)

First issue: quite often "Load and start" will not properly load the ROM, instead it will boot to either a blank screen, a Gameboy logo garbled Nintendo lettering or the ROM that was on the card before - but broken. So if I had Tetris on it and tried loading Legend of Zelda it would actually boot to the Tetris title screen, but upon pressing start the screen would garble up and freeze the system. I can even predict when this issue would appear because "erasing..." would only take a split second before proceeding to "writing...". To fix this, I need to select "Load" instead, then press start to launch the game. This will succeed when the "erasing..." takes a few seconds instead of a split second before. Maybe I am doing something wrong or this is a known issue. Any ideas? Edit: it actually seems I need to wait a few (~30) seconds before loading a rom for the erasing process to actually succeed.

Second issue: The Gameboy Camera Rom will load fine but it wont save the photos "taken". I was intending to send photos over via link cable from my original GB Camera and then be able to access the photos in the save data using appropriate tools.
However, EDGB will not save the SRAM of the ROM when selecting a new one, so the save data is never written to the sdhc. Does anyone know what the reason for this is? Does the Camera even use SRAM? Because weirdly enough I would think the battery would be dead after more than 16 years but it still holds my ancient photos.
