You mean by using Retroarch you could run these games? I am not familiar with the Retroarch. And what about stand-alone emulators? Could you please test it?
You're correct, that's using the snes 9x 1.60 through retroarch. I've also tried the snes 9x stand alone version from robert broglia (1.51), but it didn't worked, the game runs fine but with no sound.
