Alright, Colecovision Flashback is out and uh... it's okay... I suppose... it mostly works correctly.
Controller pinout is screwed up so you're stuck with the pack in controllers, which aren't all that great feeling. Most games run fine but some have missing or gimped sound. Overall sound is just a hair off but no big deal for most games. The Heist runs at half speed, which sucks.
The more I think about it, the games that are missing in my mind (Carnival, Looping, Mouse Trap and LadyBug) would probably sound like crap if Space Fury, Squish'em Sam and Zaxxon on here are any indication.
