Altirra 1.7 is released.Altirra is an Atari 8 bit Emulator on the Windows/DOS platform.Altirra emulates several models of the 8-bit Atari computers. This includes the the 800, 800XL, and 130XE versions. It has a lot of options, and compatibility is decent especially given the emulator's early stages.
