Altirra 2.0 Test 52 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 2.0 Test 52 Changelog:

Version with a fix for the change log crash: I haven't had a chance to look at the paste issue yet. I can add new memory types, but there are a LOT more than you see in any emulator. Part of the reason not all of them are supported is that a lot of them are subsets of ones that emulators already support. 192K is 64K base + 128K extended, which often works with 64K + 256K (320K). 256K is more of an oddball because it usually involves 64K aliased between both base and extended memory. I'd be interested if you find a program that specifically needs such a memory mapping as that's a good reason to implement a specific one.
