Marvel Ultimate Alliance ad hoc

Game or games this happens in

ULES00542

What area of the game / PPSSPP

I thought someone had reported this bug in the ad hoc, but no one has.

The ad hoc of this just doesn't work. When creating the room and clicking start, an error appears.

I don't know if the error is ad hoc or an error in the game emulation.

Have you checked whether your ISO's CRC is valid or not? in case the ISO was corrupted

Edit: well, this game was reported not to work at forum's Multiplayer section in the past https://forums.ppsspp.org/showthread.php?tid=9037&pid=88754&highlight=Marvel+Ultimate+Alliance#pid88754
With this error (old screenshot) taken from https://forums.ppsspp.org/showthread.php?tid=9037&pid=89082&highlight=Marvel+Ultimate+Alliance#pid89082

And nobody seems to have tested this game on the newer multiplayer compatibility list https://docs.google.com/spreadsheets/d/e/2PACX-1vRHgKsxLhnJRq6DDfgK8Z5bQMioPdUCMi5dMm9hH2Nx-DzUEd1Z8-mIlJH9BZCP9E-3uamSYp9d7ZvL/pubhtml?gid=0&single=true

Could you check the Debug Console log (from Debug menu) to see whether it's showing Unimplemented HLE function errors like in the old screenshot or not?

[CristobalManga]

I looked up how to check the CRC, and according to the results, it is the correct one.

I'm seeing Unimplemented HLE function sceAudioInputInitEx on the Host/Join selection, and got blue screen when selecting Post Game on Host menu

May be it have something to do with Unimplemented HLE, we should at least faking it to success may be.

The first break is here:

Is this divide by zero exception? Probably an assert

PS: If i replaced the break instruction with nop, this popup appeared:

If i use OpenGL/D3D11 it didn't shows any popup but bumped into another break instruction, and if i replaced it with nop too it will lead to Invalid access followed with a lot of pc address warnings.

Okay, i've tried to add a few stubs to faking success on unimplemented HLE on this PR ANR2MERefork#8
And was able to progress on Hosting Game without crashing.
