SainT is an ATARI-ST emulator running on Windows (9x,NT,2000,XP) based machines. SainT was among the first "cycle accurate" ATARI emulator. Cycle accuracy is very suitable to emulate ATARI demos. For those who don't know anything about demos, just know that's program pushing the hardware to the max. (more colors, more screen resolution, more speed, etc.). Of course SainT can run ATARI games too !
