Downloaded a bunch of Atari 2600 games and while they seem to run I cannot get the keyboard to actually control them, just see the startup screen waiting for the 'go' command. Tried return, arrows, A, everything... what am I missing?
I dunno about OpenEmu, but Stella works great here for Atari 2600 games. With the addition of some USB adapters, I can use my real Atari 2600 joysticks and paddles with it even.
