Altirra 2.0 Test 40

Altirra 2.0 Test 40 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 40 Changelog:

I got freewareCart_256K.rom to work. It is similar to the existing MegaCart 1M mapper in that it is bank switched by data written to $D5xx and can be disabled by bit 7, but it is unrelated to the previous MegaCarts. It's actually called "Megacart" with a lowercase C, and apparently was a winner in an ABBUC contest. It uses an 8K bank at $A000-BFFF and powers up in bank 0. Here's a version of Altirra that supports it. Select Megacart 1M (2) as the mapper. This version also has support for the newer MaxFlash 1MB cartridge hardware that has a different power-up bank, since I thought that was the issue before I realized what cartridge hardware was actually used. You're unlikely to encounter an image that requires it as the MaxFlash software generates carts that boot in any bank, but it's useful for testing (the first version of Sheddy's Space Harrier port didn't work on newer carts for this reason).
