I like being able to play my Atari games without a cord from my couch. This emulator is good overall but there are a few games that just won't work. The readme says certain file extensions work but I found some not mentioned that also work like .atr & .com. It also has a loading problem. I load a game & it says it can't. Then I choose another one & it will load the previous one I tried. I have an Atari 800XL & 1200XL. This emulator is taking some getting used to. I wish it just played zipped files like the other emulators.
