praetarius, a friendly request to update the rom hack's description and/or install instructions. I got v8 from romhacking.net and initially loaded it with the snes9x 2005+ core on retroarch and ran into the same issue as Layoneil. Also, while I verified the SHA-1 hash of the input rom as the one specified in the RHDN description, the SHA-1 of the patched rom is not what is in the description, it's 3975c13f1606198ff83893dbe14656dec3f7937d.
After reading this thread I tried the snes9x 2010 core and skills loaded with no problem and the game is playing well so far. Still, I think a heads up in the description would benefit others interested in trying it out. Thanks!
