Look i picked up a 21 in 1 Fami cart while i was out of town and a honney bee adapter. When i got home i realized the adapter was broken (no ribbion and wiggley) so i opened up a Gyromite Cart i had laying around (had phillips screws) after a little breaking of pegs in the cart to make room for the rest of the crap (the fami board) i put it back togeather and and put it in my NES And low an Behold it loaded up Contra?! i played for a bit and got canned before that water fall...(i know that thats sad ok?!) so i looked the cart over wondering if it really was a multicart it certanli had enough chips on it to be. So i put it back in and this time it loaded up with a menu that had 21 gmaes none of wich were Contra?! So i looked through it for a bit wondering whats up with the contra game. so i took it out of the system and loaded it like the first time it booted up contra! so i have it down to a science now weather i want to play contra or go to the menu of other games. But my question is has anyone ever heard of some thing liek this happening?
