Atari ST Emulators.
Important! The face of home computer emulation is constantly changing. Since emulation is not the primary focus of this web site, you should regard the information presented here as indicative only. Emulator authors and enthusiasts maintain their own specialized web sites with the most up-to-date information concerning their products of interest. You should rely on those sites for the latest emulation news.
ST Emulators for MacOS
There is one very good ST emulator for MacOS. Written by Philippe Gérin in Belgium, NoSTalgia is quite fast, easy to use and stable. The most recent version I have tested (0.4a1, private alpha - now a very old version) is outstandingly fast; on my PowerBook 1400cs/133 (PPC603e, 133MHz, 128K L2 cache) it is at or near original speed on many titles, even though this is a rather slow Macintosh, with particularly slow video circuitry. TOS versions 1.0x were supported at the time of review (1.00, 1.02 and 1.04), and yes this emulator supports sound. Send Philippe a bottle of wine! ;-)
The only site you need to bookmark is http://www.emulation.net/ (if you haven't already), because that is THE best source of information about ALL sorts of emulators on the Macintosh.
ST Emulators for DOS
There are a couple of DOS ST emulators, but really only one that is worth using : PaCifiST by Frederic Gidouin in sunny France. Unfortunately, the project has been abandoned; Frederic has dropped out of view.
The most reliable version of PaCifiST I have tested to date is 0.46, which runs an impressive percentage of ST software at pretty good speed. All the TOS versions I have available to me run properly, which is pleasant, and you don't need a particularly powerful machine to run PaCifiST - a 5x86 or slow Pentium will do.
STonX for DOS is another option, however it has also been abandoned. It is a port of the UNIX version, and it does have sourcecode freely available.
For the emulators above (and many games to play on them), visit the Little Green Desktop.
ST Emulators for Win32
The only ST emulator I know of for Win32 at this time is a rather alpha piece of software called WinSTon. Below is a screenshot of WinSTon running the intro sequence to Deathbringer.
WinSTon got off to a slow start; I'm guessing that the author, like me, has no spare time to work on personal projects. At this time, it's reasonably compatible though very slow, and it does have the advantage of being the only currently supported ST emulator for the PC (as far as I know). I keep both WinSTon and PaCifiST on my laptop. WinSTon is also available from the Little Green Desktop.
