Little did I know, the labelless cartridge in a big bag of Atari 2600 games that I bought at a flea market was one of the rarest games of all...Pepsi Invaders. I've had it for years and never thought much of it, come to find its worth a nice chunk of change. Anyway, I'm more than willing to part with it for the right price, so if anyone is interested, send me a PM. Thanks!
