[ATARI] Altirra 2.20 Test XVI

http://www.virtualdub.org/altirra.html

I had access to a number of 8-bit computers in my childhood, but my most favorite was the Atari 800, a 1.79MHz 6502-based computer with color graphics and a disk drive, and which as the predecessor to the Amiga, another favorite of mine. Over a decade later, I was struck by both nostalgia and ambition and started to write a new 8-bit Atari emulator from scratch. This is the result. At this point, I've learned a lot more about the Atari and Altirra now emulates more than I ever had or did years ago, but I still work on it periodically. It also serves as a modularity test for the VirtualDub code base, from which Altirra shares some components. If you are struck by nostalgia too or have a desire to do some Atari development, perhaps it might be useful to you, too.
