hey ive seen a few of these around but idk how its done or what id need to make one but u make a nes top loader out of and old nes cart. (obviously out of a a common cart) but i love ur show and think it would be a fun build. and it would help the people who can find an old nes be able to play the nes with out pirating roms and emulators.
P.S. Wouldnt it be awesome to play an nes cart on and nes cart. NES CART-CEPTION
