Summary
BizHawk 2.11.1 fails to load the CPS Changer versions of Warriors of Fate (WOFCH) and Street Fighter Zero (SFZCH).
Both ROMs immediately produce an Arcade load error with an InternalCoreException.
Other CPS1 and CPS2 games load normally on my system.
I have confirmed that the same ROM sets work correctly in standalone MAME, so this appears to be specific to BizHawk's MAME core.
Repro
- Open BizHawk 2.11.1.
- Load the CPS Changer ROM
wofch.zip or sfzch.zip.
- BizHawk selects the MAME arcade core.
- The game fails to start and an Arcade load error dialog appears.
Output
A core accepted the rom, but threw an exception while loading it:
BizHawk.Emulation.Common.InternalCoreException:
Unknown load error occurred???
Host env.
- BizHawk 2.11.1
- Windows 11 64-bit
- AMD CPU R5 5600 / NVIDIA GPU 5060TI 16G
Additional information
- The issue occurs with both WOFCH and SFZCH.
- Other CPS1 and CPS2 arcade games load correctly.
- The same ROM sets work correctly in standalone MAME.
- Screenshot of the error dialog is attached below.
