Vector graphics
In addition to the venerable Draw, supplied with every RISC OS machine, there are a number of very capable vector graphic editors and utilities.
 * ArtWorks (&pound;169.00) – Originally from Computer Concepts, and now available from MW Software, this highly capable vector graphics package is now being very actively developed by Martin Wuerthner.

 * RiscCAD Professional (&pound;30.00) – A highly capable commercial CAD package at an exceptionally good price.
 * Vector (free) – Vector and GridPro were originally developed from DrawPlus as commercial applications for 4Mation by Jonathan Marten. After Jonathan released the sources, Spellings Computer Services released the initial 32-bit conversion. The latest versions are available from the current maintainer, Christopher Martin. The sources are hosted in the SVN repository here. Vector is an enhanced alternative to Draw that offers libraries, layers and other improvements. GridPro is customised for drawing grids and other regular object layouts.

Games and Emulation
See the games page for more information on games for RISC OS.

While emulators such as DosBox or PicoDrive are mostly used to play games, in principle they could be used for serious applications as well. This is particularly true of DosBox; there are enormous numbers of DOS utilities, often old DOS command-line programs ported from Unix, that may occasionally be useful.

Compatibility
Compatibility with mainstream software, particularly certain Microsoft products, is a key issue for users of minority systems:

MS Word compatible software:
 * AntiWord – A viewer and convertor of MS Word (.doc) documents. Converts to Text or Draw
 * Writer and Writer+ can read MS Word documents with a fair degree of accuracy, and convert them to EasiWriter format.
 * EasiWriter and TechWriter can also export MS Word documents

MS Excel compatible software:
 * Schema 2 – has MS Excel (XLS) converters.
 * ViewXLS (free) – Reads MS Excel (XLS) spreadsheets. Converts to CSV, TSV or Draw. CSV files exported can then be loaded into e.g. Fireworkz for editing.

PDF/PostScript:
 * PDF (free) – Free PDF reader, based on xpdf and maintained by Colin Granville. Can export as Draw and text.
 * RiScript – Commercial PDF reader and creator
 * PrintPDF (free) – A PDF printer driver, using GhostScript as a back-end
 * GhostScript (free) – PostScript/PDF interpreter, and GView, a viewer
 * EasiWriter and TechWriter – Both programs can export PDFs, including bookmarks
 * ArtWorks – Has direct high quality PDF export, including transparency and clipping

'''Older Acorn/RISC OS machines:
 * Aemulor and Aemulor Pro allow the newer IYONIX pc and A9home hardware to access a wide range of older '26-bit' software. Aemulor was written on the assumption that some useful pieces of older software would never be made 32-bit safe and thus would become inaccessible on these 32-bit only machines. Aemulor Pro provides sound support as well, which increases compatibility to cover many games.
 * Historical note: In a similar manner, utilities such as GameOn, AutoCache, StrongGuard and other like programs helped ease the compatibility problems caused by changing over to the StrongArm processor, and before that for the changeover from Arm2/Arm3 to RISC PC. Nevertheless, some programs from the days of Arthur and RISC OS 2 will still work on every RISC OS PC and every version of the OS up to RISC OS 5 and 6.
