Altirra 2.1 Test 25 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 2.1 Test 25 Changelog:

- Now includes the 64-bit build. There really isn't much point to this since the 32-bit build is faster, but someone asked for it and I'd had it building for a while anyway. - Fix for the 16-bit cheat issue. - Fixes for some sprite issues, including the one that masked the glitch in the diarrho Quantizator picture. Sprite overlap is now supported. Unfortunately these fixes do slow things down a little bit. - BASIC is no longer shown on the caption bar for machines that don't support built-in BASIC. - Fixed a mode switch related display crash on XP machines. - Several updates to the debugger. - Fixed long filename mangling issue in H: device (it was needlessly mangling some filenames between 6-8 chars).
