Altirra 2.0 Test 47 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 47 Changelog:

Fix for a pretty nasty POKEY regression, which I only noticed because I accidentally left the emulator running in the self test for 20 minutes. It caused audio to cut out and eventually a crash. It's probably the only time in history that the built-in audio visual test has ever caught anything. I need to rework the file type association code because apparently Microsoft decided to make it extra annoying starting with Windows Vista -- I figured out that the effect you're seeing is caused by having done Open With... with the "set as default" checkbox checked. I'm seeing this be a problem with A8WP as well although it's a bit easier to go that way since Altirra deletes its ProgIDs if you disable them (which I'm unfortunately going to have to undo to make this work reliably on Vista and Windows 7). It's going to make portable installation/uninstallation more of a problem, too.
