Where Impulse Tracker was limited to i386-based systems running MS-DOS, Schism Tracker runs on almost any platform that SDL supports, and has been successfully built for Linux, Mac OS X, Windows, FreeBSD, AmigaOS, BeOS, and even the Wii. Most development is currently done on 64-bit Linux. Schism will most likely build on any architecture supported by GCC4 (e.g. alpha, m68k, arm, etc.) but it will probably not be as well-optimized on many systems.
