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?

It must be one of those games where you have to reset it to load the other game/games.

There are multicarts like that with more than 1 menu.
