In light of the recent Atari news, we've also received word that the 8-bit Atari computer emulator 'Altirra ' is now at version 2.90 containing a number of updates such as CPU: 65C816 CPU speed can now be changed on the fly without a restart, default color presets have been updated, 16-bit surface option for low-end graphics devices, and much much more that can be read in the changelog below. As for the emulator itself, it emulates the Atari 400/800, 1200XL, 600/800XL, 130XE, XEGS, and 5200 systems with full, cycle-exact emulation of all documented hardware features under Windows.
