Checklist

• Test in the latest git build in case it's already fixed.
• Search for other reports of the same issue.
• Try resetting settings or older versions and include if the issue is related.
• Try without any cheats and without loading any save states.
• Include logs or screenshots of issue.

(Assuming your ISO's CRC is good, and other CPU Cores are working fine)
Try disabling some of JIT functionality to find out which one causing the crash.

This seems related to my recent ir interpreter optimizations. Will look into it.

(Assuming your ISO's CRC is good, and other CPU Cores are working fine)

Yeah it's the same CRC as my physical copy. It works fine on other platforms, and the it interpreter on RISC-V.

Try disabling some of JIT functionality to find out which one causing the crash.

Can do if it helps narrow down the issue.

[archanox]

I just tested the JIT with everything disabled, and it errors mostly the same.

Now it says

59:19:621 user_main    E[SYSTEM]: Common/Log.cpp:73 (/media/debian/Storage/ppsspp/Core/MIPS/IR/IRRegCache.cpp:operator():806): [false] (ULUS10093 WRC, 0.4s) Unexpected type: ?

Thanks, I'll get this fixed soon.

[archanox]

Thanks, this is now resolved in the IR Interpreter.

[hrydgard]

Hm? I thought it was only the actual IR JIT that was broken, did it also not run using the IR Interpreter previously? It should have.

[archanox]

Sorry @hrydgard, right you are.
Have opened the new linked issue anyway as the problem in the title still persists.
