Altirra 2.0 Test 34 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 34:

The Direct3D 9 driver is the only one that actually supports mode switches; the GDI, DirectDraw, and OpenGL drivers don't. I probably won't be implementing that for 2.0, although I did fix the bug where the title bar was left on screen when the drivers went to fake full screen mode. There was also a fix for a pretty bad bug in earlier versions that was reported by email, which is a crash when Data Execution Prevention (DEP) was enabled. I didn't mention it in the changelist since it was only in the test releases, but I think I introduced it around test26. As for a few of the things you mention above: - The reason for putting Options under Tools is that I want to put a lot more there besides just video and error options. - I can't find any info on Injektor other than the picture of the box, which isn't helpful. If it's a standard turbo tape add-on it has the same challenges as any other turbo tape hardware modification. - As I've said, a full screen UI is a lot of work and this is not likely to come anytime soon. In particular, I do not want to put in a UI at Atari resolution (320x200) because it is usually a bad UI experience. - There isn't a lower limit on resolution in the emulator, but modern video drivers usually don't expose any below 640x480. - I don't see a point to adjusting the sound playback rate. It won't make the emulation any faster to use 8-22KHz.
