I have two Atari 2600 clones, both have about 30 built-in games. The one that I bought recently have only a few good games on it the others are just lame. The other one which I played as a kid has so much cool stuff on it, but the whole console is kinda corroded now. I think the chips on it may still be functional. So my question is can I swap the built-in games in the 2 systems? I think there could be difference in the size of the games too.Could you give me some advice on this?
