Hi, new here. Hoping to get some help. I just bought a snes and it only plays some games. The games work fine in my other 2 snes but for some reason not in this one. I've cleaned the system(pin connectors and all) and game completely. I can't figure out whats wrong. I think this snes is the 1992 gmp model.
My games and the problem i get ( all game work with no problem in other snes)
Killer Instinct (Black Screen and theme plays,No control response)
Wayne Gritzy hockey (Works no problem)
Home Alone ( nothing )
Super Mario All- Star ( Boots but no control response)
Ncaa Basketball ( works fine)
Donkey Kong Country ( nothing)
Castlevania IV ( nothing)
