So my friend sold me his N64, 2 controllers, 2 games, all the adapters, memory card and memory expansion park for 15 dollars. Heres my questions, When i'm playing Mario Kart 64 in Time Trials if I hit a bomb or fall of the track, i get a message saying ghost data can not be saved. Also when I put in Tony Hawk It won't load, screen just stays black, somtimes it playes and when it does I get a message saying memory card damaged. What do you tink of all this???
