I mentioned this over at The Retroist but I thought I would share it here too.
Robin Harbron, one of the guys that worked on the Commodore 64 All-in-One joystick, announced earlier today that his retro package "p1xl games" for iOS is free all this weekend on iTunes. I downloaded it and it's not bad. It has 4 games that look like old, C64 games. Robin has also promised that other games will be released for it through free updates.
Anyway ... it's free, and you can play it on your phone while you're pooping, so you might as well check it out.
