I don't actually know what kind of hardware setup is packed into the cartridge, all I know is that it's a NES cartridge and it plays NES games. Which is all that matters to me. I don't care if there's a fairy trapped inside that makes it all happen. Good work modder, but now I wanna see a GameBoy cartridge that plays games. Because that, my friends, would be some nanodamntechnology. I swear, those cartridges were so tiny I was always losing them -- at least that's what I though at the time. Years later I found out my older sister was selling them to buy drugs.
Hit the jump for a couple more pictures. Oh, and feel free to jump in if you've got any more info on the cartridge or if my sister sold you my Kid Icarus game -- I want that one back.
