Altirra 2.5 Test 9 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. Altirra is quite matured now, and IMO, the best Atari Emu currently! It also supports some copy protected games properly in emulation.
