By skyforbes The Hyperkin Supaboy can play SNES and Super Famicom games where you can insert the cartridges and play them.
Are there others for other old school cartridge based consoles like Atari 2600, NES, N64, Genesis, etc? I SWEAR I came across one that you can insert N64 games in years ago, but I cant remember what it's called. Do note I'm not talking about emulation, I'm talking about ones that you can insert the actual cartridges in them.
