I was just thinking,there is a lot of homebrew made for the nes but what about other (nintendo) systems?

The only thing i can come up with is a game called frog feast if im correct?

Or are there more out there? snes whould not suprise me but n64?

Beggar Prince for Genesis, and a shitton of Atari VCS stuff. Apart from that, don't know of any.

I have a list for lots of systems. Vectrex Has quite a few, Intellivision has a bit, colecovision, Atari has a ton, Dreamcast, Turbo Duo, Neo-Geo, Genesis has the one.

Oddly, enough, no sega master system games have made it to a cart release, athough, I do believe there are some roms. Most systems pre-dreamcast do have released homebrews.

frog feast for SNES

don't forget the virtual boy. there's a few homebrews that can be played on the actual system with the flashboy cart. some are pretty decent too, like blox.
