Altirra 2.2 Test 3 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. It also supports some copy protected games properly in emulation.

Altirra 2.2 Test 3 Changelog:

Portable mode fix, fix for some ROM images getting mixed up in the new UI, a couple of fixes for DOS 2 disks in the Disk Explorer, and partial save state file support. Be warned that the save state support is still not stable, though -- it doesn't do enough checks, so you can cause the emulator to malfunction or crash if you load save states into the wrong version or with radically different configurations. Currently it only checks whether the kernel ROM matches.
