Title: EverDrive-N8 PRO bug reports.
Post by: KRIKzz on January 04, 2020, 11:02 PM
This topic is for reports about glitched or not working games. Please follow rules listed below to give me chance fix problems faster.

1. detailed problem description and condition for reproducing. I should clearly understand how reproduce problem and what i looking for
2. include screenshot or video showing the problem
3. PM me link to ROM download in case if this is some hack/patched ROM or if it exotic ROM which is not included in no-intro set.
4. if problem not appears at begin of the game, but require pass few levels first, then please share save state file from the point near to the problem
5. describe your setup. OS version and console type.
6. make sure that ROM is not corrupted. GoodSet contains lot of bad roms, all those marked as [b1], [o1] and so on. At least check it on emulator.
7. make sure that problem not related to ROM region. PAL games may not work properly with NTSC systems. Also not all games working with Dendy-like clones.

Please don't post in this topic if your problem not related to certain game bugs (you can't boot your cartridge for example or some other global problems).

I have a Famicom (HVC-001) that has the NESRGB kit installed and the Voultar NESRGB-IGR switching circuit.

The system works fine with the original Everdrive N8, but with the Everdrive N8Pro it will not boot.  After spending a bunch of time with it, I was able to figure out that if I turn the power on while holding down the RESET key the cart will boot and work - BUT the system constantly palette swaps (which is normally done by holding Right one the D-Pad and press Start and Select at the same time).

If you turn the machine off and back on without holding RESET the cart will not boot.

I spoke to Voutar and got the following response:

"Sorry my man, I haven't the faintest idea with the Everdrive N8 Pro would cause that sort of behavior.
I know that the reset timings were dialed in to accommodate the original Power-Pak and the Everdrive N8, but I haven't any idea about the Everdrive N8 Pro.

-V"

Here you can see the system and the palette swap happening - the LED on the front of the Famicom is an RGB LED and each color indicates a palette.

I know that the reset timings were dialed in to accommodate the original Power-Pak and the Everdrive N8, but I haven't any idea about the Everdrive N8 Pro.

What exactly was the purpose of adjusting the reset timings? I'd try undoing those to see if it makes a difference. The N8 Pro works the same as the older N8 on a standard installation of NESRGB.

This problem not related to everdrive, same thing may happen with original cart, probably some ppu bug. It happens not always and i not sure if it related to certain hardware revision. One power cycle bug may not appear at all but after another cycle it back with various intensity.

Yeah, it is pretty random. Powering off seems to fix it for a while.

You've proved its not the n8 so I'll be quiet now  :)

I've tested out the Zelda II and I'm getting flickering lines as well. I'm using a vanilla av famicom with the pro and the flickering lines seem to be a lot worse with the FDS version of Zelda II. It's more than likely the game itself. I don't recall it happening BitD, but my memory isn't what it used to be.

I've tried as many versions of the USA rom I can find but ends up happening on all of them eventually

Also tried two AV Fami (both with NESRGB), same issue

1. Minna no Taabou no Nakayoshi Dai Sakusen does not start at all. Just load it and black screen.

2. Solstice for NES does not start at all. Just load it and black screen. The Europe/Japan versions however do start.

Tested on fw 2.03

*Edit found this on nesdev wiki...

Minna no Taabou no Nakayoshi Daisakusen    Requires that address $11 be initialized to the value $FF, otherwise the game will not start.

Not sure if that is why it's not starting on the N8 Pro, but thought it should be noted.

2. Solstice for NES does not start at all on OG v1.23 and Pro v2.05. Just load it and black screen. The Europe/Japan versions however do start.

3. Dragon Buster does not start on Pro v2.05, but DOES start on OG v1.23

4. OK, this is an odd one. The Immortal (U) works fine on both OG v1.23 and Pro v2.05 on the RetroUSB AVS, however it has an odd scrolling glitches on my unmodded NES2 and Famicom AV. (Just start the game and pause it) This is a console specific bug. Not sure how to classify that one. It works, but doesn't work on all consoles.

Post by: nuu on January 17, 2020, 01:09 PM
Did you try The Immortal on another TV when it worked?

The NES has a number of black colors in its master palette, and one of them glitches on some NTSC TVs that confuses it for the sync signal. The Immortal is one of the games using this bad color for black. Looks like there is a patch that changes the bad black to a good black:

Audio balancing is not applied to NSF at the moment. NSF uses multiple audio chips and single mapper, but system designed to set one volume per mapper. This problem can be solved using specific configuration for nsf mapper, i will work over this in future update.
There is no fds channels because all expansion chips not fits in fpga at the same time.

OK I checked out SMB2j by using an in-game level editor and removed everything obstructing so I can pass each level easily. What I noticed on the emulator is that as soon as you're done on level 4-4, the game seems to pause for a little bit almost as if it's switching disk sides. Most FDS games I think prompt you to switch to A or B, but it seems SMB2j does this automatically.
Title: Re: EverDrive-N8 PRO bug reports.
Post by: nuu on January 22, 2020, 03:51 PM
SMB2j is a 1-side disk game so you never flip the disk. The RAM adapter is too small to load the whole disk side though so it loads only 4 worlds at a time. This is why it pauses after beating stage 4-4, to load worlds 5 to 8.

Really? If that's the case then the game is going to lock-up on two more occasions on the N8Pro. Right after you beat 8-4 (to load the ending) and the other after you beat the game eight times and try to load worlds A-D (both have the exact same pauses)

*Edit ; Yep, sure enough. Attempted to load my eight-star SMB2j FDS file, and it froze when trying to access worlds A-D just as it does after world 4-4. Can I upload the modified ROM? (It's really just a template, all the levels have been removed and the flagpole is right at the beginning in most levels)

Post by: nuu on January 22, 2020, 08:03 PM
So it freezes when trying to load anything at all except for the initial boot load (which only includes worlds 1 to 4). I don't think it needs to read the disk just for the ending music or does it?

If I had to hazard a guess it pauses exactly 4 times in the entire game. Once after 4-4 (to load Worlds 5-8), Once after 8-4 (to load the ending) Once after going through the entire game without warps to load World 9, and finally at the title screen by holding down "A" after you beat the game eight times to load worlds A-D. That's how many I counted going through the entire game.

I suppose it's technically 5 if you count the initial loading of the game.

Ok, if you tested it I guess I'm wrong.

If you are not comfortable uploading the hacked fds image, just upload an IPS file. You can make one easily with Floating IPS for example.

Alright so I removed any and all levels with the editor. Should be easy to test all the possible points it pauses to load. This file is what FCEUX spits out after you beat the game once. (it just copies the .fds file) It should have all stars on the title screen and just hold down "A" when you hit start to access worlds A-D. The longest to test will be world 9 since you have to go through all eight worlds without warping to get to it (the flagpole is at the beginning....but you'll get tired of seeing that course clear countdown) The level of -4 still has to be run completely but it just means you'll be dashing until the end. There is a Bowser at each end, just save state before each one just in case.

Post by: nuu on January 26, 2020, 03:39 PM
Thanks! I tested it in Mesen and unfortunately it doesn't appear to simulate the disk access LED on the disk drive, so there was no way to know if it accesses the disk for sure. But it does pause with a black screen at some points so I'm pretty sure it's accessing the disk at those points to read or write to it.

I should just explain how the disk system works: The BIOS reads data from the disk to the RAM adapter at boot (files to be loaded by the BIOS is specified in the game's disk header). After that the game is fully playable like a normal cartridge game since it's running on the RAM adapter (which works just like a normal game cartridge as far as the Famicom is concerned). The disk drive doesn't use any power at this point (which is why batteries lasts so long) and you could even unplug the RAM adapter. As soon as it needs to access the disk (either for reading to load more data or writing to the disk to save data) it must be plugged in and powered though. When it does, the red LED lights up on the disk drive.


With my observations using this hacked disk image in Mesen, the number of points of gameplay it needs to access the disk, not counting the boot load, is 5 (although it may vary depending on how you count):

 1) After saving the Toad in stage 4-4, to load worlds 5 to 8.
 2) After reaching the door at the end of stage 8-4 and D-4, to load the
    ending.
 3) After the ending, to write a star (8-4 ending only) and to load world 9
    (8-4 ending only and only if all Toads are saved).
 4) After the ending of 8-4 (only if not all Toads saved), after the ending
    of D-4 and after a miss in world 9. In all cases to load title screen and
    worlds 1 to 4.
 5) When pressing A+START to enter the letter worlds (requires 8 stars).

Also to be noted that maximum amount of stars is 24 (18h) The game still pauses even if you have the maximum amount. I probably should've uploaded that save (you can still change it in any file, open up the file and change $CC2C to 18) Regardless though it should make it easier to test out the game (special thanks to ALXR of romhacking.net for his SMB2j utility)

interesting! it would be interesting to have a way to select a specific player, for example, if you only use 2a03 and fds. but either way, it's good to hear you'll be working on the volume issue!

Might want to change that SMB2j for the FDS to "partial working". It does indeed work, but only up to a point. The game will lock up at various points after World 4-4, accessing special Worlds etc. Even though the game is one sided, it still internally loads data (I think it loads things like upside down pipes, wind effects etc.....which are only featured on worlds 5-1 and up.)

*EDIT Oh and thats for the original N8 and Pro

Re: Dead Zone on FDS, I've been trying to play the recently released English translation on my OG EverDrive N8, and while it technically works as indicated, you cannot save without switching to Side A, and  it is somewhat critical to save often in text adventures.

I think disk sides are stored in FDS image files sequentially, this includes additional disks in multidisk games: 1A, 1B, 2A, 2B etc.
There are no games that spans more than 2 disks (4 sides), but there is technically no limit and a possibility for homebrew to have more. I don't have a pro yet, but I imagine that if you are on 1B on a 2-disk game and needs to return to side A to save, you would need to press the button 3 times to go back to 1A (or however the disk swap works).

In that compatibility list, what is the problem with the Famicom Mukashibanashi games, the Famicom Tantei Club games, Tantei Jinguuji Saburou and Time Twist? If the FDS button works as it should, it should be possible to switch to any side at any time like on a real FDS, that's the point of the button.

I don't know how multi-disk games work, so I did not test them myself on the Pro, but the red for them just means that trying those disks by themselves they don't work, obviously since they are the 2nd or 3rd disk.

Another small FDS issue, save states do not work with Fire Rock.

Post by: nuu on February 11, 2020, 12:47 AM
OK in that case it's not a problem at all. The second disk in multidisk games are generally not bootable, although they could be. If you try to boot the wrong side you would get A. B. SIDE ERR at least.

Can you check the headers on Scheherazade?  I don't have a hidef yet, but I can load the ROM on my N8 Pro okay...  Should be 128k PRG / 128k CHR ROM without any WRAM/SRAM/CHR RAM...

I checked two different Magic of S. roms and both had 8 banks of 16k PRG or 128k and 10 banks of 8k CHR or 80k if I'm interpretting the header correctly.
Header in Hex is 4E (N) 45 (E) 53 (S) 1A ( | ) 08 (128) 10 (80).

Ran into a strange issue that has ONLY been happening with the Everdrive Pro. I've tried 2 different ROMs of Super C. I can't reproduce it on my original Everdrive and it's never happened with my original cartridge. It's happened 6 times now i believe, sadly all on good paces while on stream ;_;
I highlighted a full run to this point with reset in case someone can maybe see a reason?

The glitch itself happens with the Stage 5 boss, it begins to screen wrap and is near impossible to kill in this state as it's hitbox seems to shrink and become invisible XD
In the video the problem becomes clear at 9:45 but i did also notice some odd behavior in item pods back on previous stages.

I realize this is an odd problem but I feel like i've done all i can to know that it is only happening with the Everdrive Pro for some reason. (Using V2.06)

I was just able to reproduce it again. I took a save state and was able to recreate the issue several times. However, upon doing a full power off of the system and loading that save state, the boss was fine. I think this would indicate something is becoming corrupt in RAM somewhere along the way?

I use an RGB Front-Loader with the Everdrive Pro. Made another highlight of this. I suspect the bug begins during stage 4, 8 seconds into the video you can see the balloons act very strange. They do this again on the climb in stage 5 at 2:43. At 4:55 you can see the ultimate form of the issue with triple vision lol. https://www.twitch.tv/videos/559397808

Action 53 Vol 3 (and the upcoming Vol 4) reported as not working on the Pro.

These utilize mapper #28, the Action 53 mapper.

After reviewing this documentation (https://github.com/krikzz/EDN8-PRO/blob/master/mappers/002/map_028.v), developer jroatch made the following comment:

Quote from: jroatch
…it looks like it limits its total ROM size to 512KiB by only having 5 bits for the "outer bank".

Attached is the Vol. 3 ROM along with a special test ROM.

Vol. 4 ROM is larger than attachment limit, but I can email it if requested.

Set the submapper to 1 in the header and your problems will go away.  You can apply any or all of the Statropics hacks if the header uses Mapper 4, submapper 1.

Hi! Thanks for the great product. Unfortunately I'm running into a little weirdness with the NSF player occasionally. Sometimes when you move to the next track, if a sound was looping and the next track doesn't use the channel it will still continue to play. Please try out the Legend of Zelda NSF from Zophar and skip to the end of the tracklist to the FX, you should hear the dragon repeatedly roar over the other tracks.

45-in-1 (Unl) (As) [f1].nes is the correct iNES but those mapper settings are not quite correct.  You need NES 2.0 header (Extended iNES in Nestopia) to designate 2048KB of CHR-ROM.  It does not matter anyway, because even with the correct header I get a garbled image.

The maximum specification of iNES 1.0 is 4080KiB/2040KiB PRG/CHR.  The maximum specification of NES 2.0 is 65,520KiB/32,760KiB PRG/CHR with the regular size method and 64,563,604,257,983,430,656bytes/64,563,604,257,983,430,656bytes with the alternate size method.

Title: Re: EverDrive-N8 PRO bug reports.
Post by: MHzBurglar on May 30, 2020, 10:02 PM
I recently bought an Everdrive N8 Pro, and it has been working fine up until today.  Now, for some reason, I always get a solid grey screen when I turn my NES on, and I have to press reset to get the EDN8 Pro to actually boot.  It used to boot immediately without any issue...  Regular NES carts boot up right away, so it's just the Everdrive doing this.  I updated the firmware to 2.08 last week, but it's was working fine until today.

Any idea what's causing this?

Edit:  Just to test, I took the Everdrive N8 Pro out of my NES, unplugged the system, and pressed the power button to drain the residual power from the system.  After I plugged it back in, the EDN8 Pro started booting immediately on power on again.  Very strange.  At least my cart works just fine once it does boot.

Edit 2:  It happened again after the power cord was accidentally pulled from my NES while it was running.  This time, the 'power drain' trick on the NES didn't stop the grey-screen boot from occurring, but it did go away after leaving the EDN8 Pro disconnected from the NES for about half an hour.  After that, it was working perfectly again.  I thought it might have had to do with some kind of residual power in my NES/NESRGB board, but maybe it's actually the EDN8's FPGA that needs to discharge.

Hopefully this will help others who are seeing this issue.

I got brand new N8 Pro and RetroUSB AVS console couple of days ago. I added some European and USA roms into the N8 Pro and couple of days everything worked just fine. I played around 20 different games without any problems. However yesterday when I was playing Star Wars the system crashed (I did not use save states). I thought it was just a random error and after I tried the game another time, it worked well. Today I was playing Super Mario Bros 3 and it crashed same way as Star Wars. I booted the system and continued playing and the game crashed again. Before that I had played SMB3 several hours and used save state to save my game (I used only one save slot for several times). I would like to know if there are some known bugs in latest firmware? I think this issue is somehow related to save states because when the crash happened, the save state window popped up automatically during playing. This problem has happened only with Star Wars (Europe) and Super Mario Bros 3 (Europe).   

After the Super Mario Bros 3 crashed today, I formatted my MicroSD and started from the beginning. After that I played Star Wars maybe 15 minutes and played Super Mario Bros maybe 1,5 hours without any issues.

N8 Pro has latest firmware.
AVS has latest firmware.
AVS is connected to wall socket by using the USB cable which came with the console.
I am using original NES controller with AVS.

Do you think this kind of crashes are usually related to charger (or power anyway)? I read some old topics and noticed that there was some discussion about power problems with AVS...

Actually I already changed another charger (some ASUS tablet charger) and played Super Mario Bros 2 and Super Marion Bros 3 and those both worked well. I should also have some other high quality chargers (at least Nokia and iPhone) and must try those if the issue still exists.

Recently got a new Famicom N8 Pro, an Analogue NT (not mini, using HDMI out), and a RetroUSB AVS.

The N8 works on the analogue NT but acts buggy occasionally.  I ran a diagnostic on it and the diagnostic hangs at IO RD speed every time.  Have to restart the console.  Tried this with RetroUSB AVS and diagnostic shows no issues. 

I guess the question is....Is this an issue known with the Analogue NT?  The fact that diagnostics run fine on the AVS make me concerned something is wrong with the NT.

The N8 has compatibility issues with the original NT. Do a search and you’ll find the threads. I finally sold my NT and got a NT Mini for this exact reason.

Today it happened when I was playing Aladding and Jungle Book (both were PAL games). Now I must try older firmware and tomorrow I will go and buy a new microSD card if the problem is somehow related to my memory card. In any case I am not happy with this situation.

Yes, I am aware of this note about latest AVS firmware and likely will contact RetroUSB. However Mega Man 5 is mapper 4 and Aladdin is mapper 7 and it is not a big deal to test this, if someone has same hardware with same firmware.

No special guide about downgrading AVS firmware. It's done the same way as upgrading using the scoreboard program. Firmware can be degraded using the older firmware files and using the same process used to upgrade. Firmware can be upgraded back to a later version again too.

Thank you! I will try rollback v1.30 and see what happens.

EDIT: It seems changing firmware did not solve the problem. Quickly tested Aladdin and now it crashes at the moment when the first stage starts. Must send email to retroUSB and ask if they can develop PAL support. Maybe especially mapper 7 is problematic somehow. Another mapper 7 game is Battletoads. It looks right when using US version but in PAL version the top of the screen is cut off.

Of course it would be great if these games can be checked in Everdrive side too.

I wrote some time ago about crashes that I have experienced especially with Aladdin but with some other PAL games too. Previously we thought that the problem was RetroUSB AVS but I am pretty sure that the problem is, at least in touch with Aladdin, somewhere in Everdrive N8 Pro software.

Aladdin game crashes every time when I try to create new save state. I have now tested following setups:
1. RetroUSB AVS with Everdrive N8 Pro (AVS with couple of different firmwares)
2. RetroUSB AVS with Everdrive N8 Pro Famicom
3. Original PAL NES with Everdrive N8 Pro

Everdrives has latest firmwares.

Same issue on every combination.

I have played lots of NTSC games without any problems. So this is just FYI if you have some time to investigate the problem. This is not big issue for me because all NTSC games works without any problems. :)
