So I ordered up one of the 111 in 1 Neo Geo MVS carts and a few of the games appear to be buggy? When my sone tries to play Metal Slug 3 and some of the fighting games he gets randomly booted back to the menu screen. I have a single slot Neo Geo MVS Jamma setup. Any clue if this is a bad cart or a common issue we just have to live with for purchasing a hacked cart. My last thought is the buttons on the cab are fairly old and may be sticking just a bit, I have new ones I'm going to install this weekend and see if that helps anything.
