Atari++ 1.59

Saturday, January 8th, 2011

New version of this Atari Emulator. The Atari++ Emulator is a Unix based emulator of the Atari eight bit computers, namely the Atari 400 and 800, the Atari 400XL, 800XL and 130XE, and the Atari 5200 game console. The emulator is auto-configurable and will compile on a variety of systems (Linux, Solaris, Irix).

What’s new:

- Fixed the Antic DMA cycle allocation for narrow playfields. Due to misalignment between various DMA allocation slots, more cycles were available to the CPU than possible in the original hardware.
- Added a cycle-precise Pokey emulation that updates interrupt registers and potentiometer registers on a cycle-by-cycle basis.
