"Wolverine - Adamantium Rage (USA)" hangs on the latest master version

[Screwtapello]

As reported by user usVSthem on Discord, the USA version of the game Wolverine - Adamantium Rage hangs after displaying the unskippable developer and publisher logos, but before displaying the title screen. The European version, and the Japanese version (just named "Wolverine") both work fine.

Bisecting history points to 4f7a269 as the commit that introduced the problem, which changed how bsnes handled joypad polling - which makes sense, since it's only once the game tries to interact with the joypad that the problem occurs.

Note that this commit fixes the game SpellCraft - Aspects of Valor, so whatever we do here has to make both games work - we can't just revert this specific fix.

I believe the same game works fine on ares, even though ares has exactly the same HVBJOY code. Clearly there's some other difference in the SFC emulation.

From the issue about SpellCraft - Aspects of Valor:

@asuramaru said that their fix in bsnes was subtly different from @jbo-85's fix in higan, and if a game ever worked in one but not the other, that would be a clue to which implementation was more correct

I should test SCAoV in ares to see how it holds up.

I suspect the higan commit being referenced is higan-emu/higan@e422ddc which is a much more complex change.

Good catch on this @Screwtapello ! Hopefully a solution will present itself soon!

I wonder if this issue is why you can't register your name on bs legend of Zelda. You can move the cursor but there's no response when trying to register your player.

Has @carmiker seen this yet? He seems to be very familiar with bsnes code.

Edit** tried using a newer version of the bs Zelda roms and this problem doesn't happen or persist.

[carmiker]

I am aware of it, and hope to fix it.

[joepogo]

I have found at the moment it seems a workaround is to overclock the CPU by any percent and the game will be playable until it's fixed proper.

Apparently Mesen has done more research into autopolling behaviour, including a new test ROM, as mentioned in ares' issue tracker: ares-emulator/ares#970 (comment)

Yes, and all the problematic games we had back then work without any issues with Mesen. If someone wants more context, they should go to the snes development server discord, channel "emulator dev" December 2024 posts.

I've got 3 more tests to write after Christmas (to test writing and reading JOYSER0 during autojoy).

After that I will rerecord the test outputs and post them all to my website.

[undisbeliever]

Just want to let you all know the tests and console recordings are going to be delayed a bit. Fiskbit came up with 2 more autojoy tests and I would like to publish all of the autojoy tests at once.

Here are the auto-joypad tests from undisbeliever: https://github.com/undisbeliever/snes-test-roms/tree/master/src/hardware-tests/auto-joypad
