Hello all,
I received a copy of famicom Gun Nac from eBay ... however, the game has graphical glitches when I try to play on my US NES and Twin Famicom. Upon startup (on the company logo screen), there is a grid of red dots surrounding the logo. Also, when playing the game, the same dot pattern appears on larger sprites.
Does anyone know what the problem might be? Cleaning the game?? Something else??
Cleaning contacts should help.
