Soulcalibur hangs after the first round against Inferno #7

Closed Senryoku closed 1 month ago

Senryoku commented 7 months ago

In arcade mode, after winning the first round against Inferno, the game hangs. I guess it has to do with the way its moveset is randomly selected? (It's not random for the first round IIRC)

Senryoku commented 7 months ago

Setting the number of rounds to one allowed me to finish the arcade mode. Pretty sure it has to do with swapping movesets.

It's stuck on "Now loading...", I don't see any GD-ROM access, but I might just be missing some logging. Or it's something else entirely.

There some GD-ROM access right before the freeze, but they use the usual syscalls:

The intro cutscene is also cut short after some DMA, I wonder if this is linked?

Also, the boot ROM hangs waiting on something, and in this case I very, very strongly suspect this has to do with the GDROM.

Dumping a trace here (I lost the trimmed and annotated ones I worked on before :')) Inferno.txt

Note that this also happens using LLE bios (and that switching to the interpreter during the freeze doesn't help).
