RISC OS
Old ARM/RISC OS software, no longer maintained and generally not 32-bit compatible. Released with source (mostly requiring the BAX extended compiler) under a new-BSD licence (you can ignore anything about licensing, or old contact addresses, in the documentation).
- BombScare: logic game
 - EliteExt: silly extensions to ArcElite
 - The Hacker: game-cheating app, including the GUI-based 3.10i release as well as the command-line-based 2.02. Not natively RISC OS 3.5+ compatible, but should run on Risc PCs with the ARM Club’s Game On! utility. Note: its successor Desktop Hacker is still available commercially, updated for RISC OS 4 compatibility, on the RISC User ...in a Nutshell CD from R-Comp Interactive.
 - MZXiface: Multiface POKE utility for RISC OS Spectrum emulator MZX.
 - NewerLook: complete replacement desktop look and feel (including other components previously released separately).
 - PaletteDM: adds the missing desktop palette and gamma correction editing features to the Risc PC Display Manager utility.
 - ShiftKeys: desktop accessibility tool.
 - WimpSWIVe: programmers’ utility module. Version 0.05; Andrew Booker has since produced an updated version for RISC OS 4 and 5.
