Wow, that's not something you see every day.

That's right... It's an entire NES stuffed into a super mario cartridge. That's pretty ironic huh? Has the whole works, all the ports etc.. even a power switch. It's pretty awesome, only thing I would add is the ability to use batteries. Maybe a little LCD screen too.

Found this little gem while "stumbling" :P
