Emulators Online - Atari 8-bit Emulation
The original Xformer project began in 1986 as an effort to run Atari 800 BASIC on the Atari ST desktop computer using emulation to translate the 6502 machine code of the Atari 800 to the 68000 machine code of the Atari ST.
In the past 32 years since, Xformer has been ported to the Atari TT, MS-DOS, Windows NT, Windows 95, Windows 98, Windows 2000, Windows XP, and Windows 7 making a total of 9 major releases across multiple platforms:
ST Xformer is the original version for the Atari ST, STe, and Atari TT and was the first version to support the Xformer Cable for connecting Atari floppy disk drives to the emulator,
Xformer Classic was a major port from 68000 based Atari computers to Intel 286 based PCs and runs on MS-DOS, Windows 3.1, and OS/2 and also supports the Xformer Cable,
Xformer 2000 which runs on Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000 and Windows XP offers enhanced sound and joystick support, and replaces the earlier Xformer 98 emulator for Windows 98,
Gemulator 9 (the 9th and most recent release in 2008) combines Atari 8-bit emulation and Atari ST/STe emulation into a single emulator for use on Windows XP, Vista, and Windows 7 and support for running on both 32-bit and 64-bit Windows operating systems.
ST Xformer, Xformer 2000, Xformer Classic and Gemulator 9 are completely free and have been available for download from this web site for many years. And that now includes the brand new Xformer 10 release for Windows 10.
