Hey, is this really supposed to be applied to the v1.0 Japanese ROM as the hash data indicates? That seems weird to me because the original J2E patch used the v1.1 Japanese ROM.
Uh...I dunno?
I've had probably the worst real life stuff go down since posting this. I dunno. Does that work? Or shouldn't it?
I am too mentally slow right now to even know where to start, I'm sorry. 
Yikes! Sorry to hear about the real life troubles.
I applied the patch to both the 1.0 and 1.1 versions of the ROM and both seem to load correctly using the bsnes compatibility core in RetroArch. So perhaps they both will work? I'm going to stick with 1.1 for now since the original J2E patch was based on that version.
