Already did so. I posted it on romhacking.net's forums but here it is,
The changes likely break the original Japanese version though, so it's not something to be merged into the main repositories.
EDIT: Also, it's important to realize this patch isn't doing anything real hardware can't. The reason we need to modify the emulator is because 99% of all SNES emulators rely on a built-in database to assign a circuit board configuration for the game (something real hardware can read via the physical cart). The translation made changes to the memory mapping and thus broke this internal database check.
Higan/Bsnes is actually smarter about how it assigns this configuration and lets you read a custom cart-map in the form of a .bml/.xml file. This tricky situation illustrates the value of Higan's often criticized ROM format.
@Burnt Lasagna could you please share the changes you made in snes9x gx 4.3.7 to make Tengai Makyou Zero work again? The download link is not available anymore. I would like to look into it because I backported the changes from snes9x to get pastthe blacl screen so the game starts. The only thing that is not working is the Real Time Clock. Thanks in advance.
