EverDrive-N8 PRO bug reports.

[lee4]

Today I played several hours and tried many games (Jungle Book, Aladdin, Mega Man 6, SMB3, Power Blade). It seemed that everything is fine because I did not experience any issues until I tried to use save states in Aladdin. It seems that the game crashes every time when trying to use save state. Attached is the picture which tells what happens when trying to save or load previously created save state.

I would really appreciate if you can try to repeat this issue.

Rom: Aladdin (Europe).nes
AVS firmware: v1.40b4
N8 PRO firmware: v2.08

I dig up AVS changelog and what I see this:

1.40b4
  Fixes boot to black screen issue in Mega Man 5. May break other games!

You will need to contact RetroUSB about incompatibility issue

Try older firmware

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. If someone can reproduce this, I know it is software issue and my N8 PRO and AVS are physically ok. Btw, do you know if there is some guide, how to downgrade AVS 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.

Solved,although I donnot know why, what I did in sequence is
1. OS 2.00 Expansion joystick not worked
2. Download 2.08 and unzip ,Expansion joystick still no response
3.Change 2.02 then 2.07, all is OK
4. Back to 2.08,joystick works.

New FC with OS v2.08
