I once played a (homebrewed I think) Jetpack game on the GBA.
It was terribly simplistic, had crude graphics (Your character was nothing more than an upside down L) and was as absolute blast.
Think destructible environments somewhat similar to minecraft in an Atari setting with rockets, floating mines and C4.
I'm sure it's been modded in multiple games and simply not noticed.
