Title says it all, pretty much. I made sure to patch the correct CRC as indicated on the RHDN page. The game displays the TOMY splash screen, then locks up - I tried every SNES core available in Retroarch and got the same result. The unpatched game boots fine, so it's definitely an issue with the patch doing something that, most likely, worked in ZSNES back in the day but which won't work on hardware.
So, my actual question is: is there a sufficiently old emulator other than ZSNES that I can actually play this with? Or am I stuck using that old dinosaur?
