DosBox
DosBox is an x86 emulator with up to VGA graphics and sound. It is licenced under version 2 of the GPL. The latest version available for RISC OS is version 0.63-1, as part of the Unix Porting Project. On a high-end PC, DosBox can emulate a fast 486 or early Pentium machine. On an Iyonix, games for the 286 and some 386 games should be playable. Performance is relatively low because the Arm processor has to do more work to emulate an x86 processor successfully. On the x86 platform, even when running Linux, emulating DOS on an early x86 processor is a simpler task.
The DosBox !Help file explains how to set up sound and how to map a RISC OS directory as a DOS drive letter. CD support is also available (? I believe - haven't double-checked. Simon Smith 19:28, 27 July 2007 (BST))
