Altirra 1.9 Test 11 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 11 Changelog:
- System | Audio | Audio Monitor now enables an on-screen display of the four POKEY audio channels.
- Tools | Disk Explorer lets you drag files in and out of disk images. A few caveats on the Disk - Explorer, currently: it may act badly if you give it a disk that isn't DOS 2 or SpartaDOS format, it shouldn't be used on disk images that are currently mounted, and be careful when modify disk images as there are probably still bugs in the write support.
