Hi, thanks for your feedback, I tryied the Great American Cross Country Road Race and it worked like a charm. Of course using Karateka, I tryied all the possible settings (Cooked or raw keyboard, map to another key and back to arrow key, and other combinations), but can't make this works ... I'm using a Lenovo Yoga 13 with Windows 8 64 bits, and tryied the 32/64 bits of Altirra 2.30.
Thanks,
ATARI
