I second Wild Arms here; the music is fantastic and the game itself is pretty enjoyable, just remember that you can throw your rat at people, otherwise you'll get stuck where I did as a kid. >: I

Also, I don't know which SNES emulator you are using, but if it is the SNES9x port I've had it crash during long RPG play sessions, which wipes all of your progress since the battery doesn't seem to save until you exit the emulator, so heads up on that potential issue. I lost a ton of progress on my RS3 team-fisticuffs playthrough to that once. ; -;
