As the title says.
LinkI'll list them all here, as I doubt anyone would know where all of them are from:
Atlantis (Theme Hospital)
Chai Kingdom (Super Mario Land)
Come Out and Play (The Offspring)
Exed Exes (Re-edit of the original version)
Hogan's Alley (Looped remake of the original)
Jurassic Park (From one of those Famiclones that Taizou has)
Menu Theme (Made it up, not the one off that 105-in-1)
Papillon (The Sachen game)
Pocket Zaurus
Robocop (The NES version)
Running in the 90s
Slalom (NES game)
Streets of Rage II Track 14
Take On Me (Thankfully not as bad as the Beat N Box version, although it'd take a fair bit of effort to do worse
)
