M1 - The best sound emulator, supports loads of systems/games as well.

Nebula Jukebox - Good, fairly specific to a handful of systems.

QPlayer - Out of date.

Hoot - Overcomplicated, almost impossible to use

Amuse - Now been superceded by M1, not sure if this ever got an official release...

Cheers,
