Altirra 2.3 Test 6 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 2.3 Test 6 Changelog:

Debugger: Fixed disassembly of PEA ($F4) opcode. Debugger: PHX and PHY no longer create bogus call trees in the History window in 16-bit indexing mode. Debugger: Fixed disassembly of opcodes with the (d,S),Y addressing mode. MMU: VBXE can now properly overlay Covox. VBXE: Writing a '1' to the blitter start bit no longer aborts an active blit.
