1.12. On what platform does Exult run? 
Exult should be able to be compiled (with minor modifications) on any platform that SDL supports. Right now the source can be compiled in Linux/i386, Linux/Alpha, MacOS (requires at least MacOS 8.5 or higher), OSX, OpenBSD, FreeBSD, Solaris, BeOS and Win32 (Windows 9x/ME/NT4/2000/XP). 
Ruediger Hanke's ported Exult to MorphOS and AmigaOS. You can get this version at 
http://www.muenster.de/~tomjoad/exult.html. 
Recently Artaxerxes started working on a port for Zaurus, a Linux/ARM based PDA. It is already fully playable (Artaxerxes played through SI). Pictures of the Zaurus running SI can be found at 
http://exult.sourceforge.net/images/screenshots/zaurus/ and an IPK package at
