Hello, all. Lately, my Master System III Compact has been going through a strange phenomenum. Whenever I press a button repeatedly, and only when I do it very fast, the controller loses input for about half a minute, then it all returns to "normality". I've tried my games with different controllers, and the same thing happen to them all. Gauntlet and the sidewalk skating in California Games are the games in which this usually happens, but it sometimes happens with other games too. Since I'm pretty sure the problem isn't the controller itself, what else could it be? The controller connector? Some RAM related problem? A motherboard problem? What could be the cause?

Don't know much about the master system III, but the symptoms you describe - something that wears off over time - is likely indicative of either an overheating issue or some issue involving capacitance. Perhaps the III has some capacitors on the I/O port for debouncing or something and they are starting to fail. The caps are normally what goes first on older consoles.

Thanks for the info, Will. I don't have the guts to mess with soldering, but I think I'll have to do it sooner or later, huh?
