Didn’t know about this. Agreed on the selection of games being pretty bad. Doesn’t bode well for a mini Atari 800, which would have pretty much the same game options.
If memory serves, Temple of Apshai required that you own a booklet that had the room descriptions in it, containing all the usual dungeoneering clues for DM would give you. Is that just ignored here? What a drag.
For me, the point of machines like this is the controllers. Games written for the Atari consoles, Atari 8-bit computers, and the C64 were written with the Atari joysticks and paddles in mind. I do have a a cable that converts Atari controllers to USB for use with a PC emulator, but I’ve never used it and don’t even know if it works (because I have a 7800 and plenty of good controllers).
