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!

Changlog:
AVSchanges.txt

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.

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.

I will look on this game when i will work over next os update

Any chance to inspect it in next realease?

Laser Invasion no longer crashes with OSv2.10 at the LaserScope test screen, but it does flash a frame of junk graphics when the options menu is shown.  Updated spreadsheet of issues :

Just a heads-up in that while working on Nt Mini Noir settings for cart audio, Ace and I discovered the VRC6 emulation in the Famicom N8 Pro has one or both square waves inverted compared to an original cart of Akmajou Densetsu. I recorded the first stage music and Ace found the inversion happening upon visual inspection of the wave peaks. I checked the area myself in the track and confirmed the waves are inverted. We believe sawtooth is fine, so it appears to be one or both square waves.

Here's a combined recording that makes the visual inspection easy, as it contains original cart audio in the left channel, and Famicom N8 Pro audio in the right channel:

Specifically go to the 32 second mark and from there on you can see it most blatantly.

I don't know if this is a EverDrive N8 Pro bug or a bug with the CIC implementation of the Blinking Light Win, or a combination...

But turning on my NES with the BLW and the N8 Pro results in a blank screen, and only works after turning on and then resetting once. Resetting again does work, using back to menu / exit game also works, so it's not a major problem.

My other NES without the BLW works immediately always. Both machines have had the pin 4 snipped on the original CIC. And both machines work with original cartridges as well as the original N8.

Having many issues with Zoda's Revenge Star Tropics 2

N8 Pro v2.10
NT Mini Noir Jailbreak v6.5
v2.0 headers
Seems related to using save states, but not sure.
(edit, I'm leaning heavily towards a copy protection issue now)

1st issue... after completing Star Tropics 1 I used N8 Pro menu to load Star Tropics 2 only to find grey screen and game "resetting" over and over similar to when an old NES would flash its power button on a bad connection.

Only thing that worked was powering off NT Mini Noir and then trying again and then I was able to load Star Tropics 2... I was then able to play to the end of Chapter 3 (collecting 2nd tetrad).  The game then played the cutscene transition to chapter 4... only right after it completed I got booted to title screen of game as if I had hit reset.  Loading my save state back to just before collecting the 3rd tetrad played out the same except instead of title screen I was back to grey screen with "resetting" behavior again.  Powering off NT mini noir and load state again and same issues.... either title screen or resetting grey screen.

Next step is I'll attempt to load from regular save and not use save states after a power cycle.

if that fails I'll try and provide files and video, but hoping this is a know issue with a fix??... because at this point I'm literally stuck with no way to continue.

Edit...
***Found this in the Star Tropics 2 wiki... Seems extremely similar to what's happening with me... Thoughts?
Copy Protection
This game has a couple of copy protection checks preventing the game from being modified. First, when the game boots, the copy protection code calculates a checksum for two title and intro data blocks, as well as some CHR data. If these tests fail, instead of seeing the title screen, you'll see the screen flicker back and forth from black to white, once per second, accompanied by a sound effect. After about 5.5 minutes, the title screen will appear, and the game will start as usual. To force this screen to appear, use the Game Genie code EYOVSZEI. The blinking effect may have been intended to simulate the effects of a bad cartridge connection, where the console's lockout chip continuously resets the game, though the reason for the sound effect is unknown.

Another integrity test for one of 16 predefined data/code chunks is selected randomly and performed when switching to the next chapter of the game, starting from chapter 5. If this fails, instead of the next chapter, you'll be returned to chapter 2.

A copy protection that waits until chapter 4? Sounds a lot like what is used in the Earthbound games.

If I were you I would try it with the save state feature disabled and see if it still triggers the copy protection. As long as the N8 Pro is doing something it shouldn't, it should work.
