Altirra 2.1 Test 30 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 30 Changelog:

looks like Intel cut corners on texture shaders. It switches to a pixel shader 2 implementation when possible, and hopefully it will work around the problem.
