Altirra 1.9 Test 9 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 1.9 Test 9 Changelog:
First shot at PAL high artifacting. It is not optimized yet, so it runs slowly, but the basic method is there. Starting hue is not controllable. The main issue with this method is dot patterns on sharp color edges; this is related to per-line chroma V inversion. Not sure how to solve this yet.
