As a random aside, I find it interesting how rarely SNES pirates ever made their own music.
And also as a random aside, every single SNES pirate that I've ever seen steals either its music or its sound engine from Capcom. Aladdin, obviously, steals the music from Aladdin; the two Pokemon games steal music from Bonkers; and many of the fighting games have music stolen straight out of SF2. But even the ones that do have original music (e.g., Pokemon Stadium and Super Big 2) have a sound engine stolen from Super Pang.
Edited to add: Pirates have been using the Super Pang sound engine for a good while, too. "Gamars Puzzle", one of the first unlicensed things known for SNES (it's a 9-piece picture puzzle from the BIOS of a ROM dumper from 1994!), uses the samples from Super Pang at the very least.
