Open Source RISC OS System Software

VICE is an emulator collection which emulates the C64, the C64-DTV, the C128, the VIC20, practically all PET models, the PLUS4 and the CBM-II (aka C610). It runs on Unix, MS-DOS, Win32, OS/2, Acorn RISC OS, BeOS, QNX 6.x, Amiga, GP2X or Mac OS X machines.

CrossBrowdy is a free and open-source JavaScript framework that allows to create multimedia apps, emulators, game engines and games that will be compatible with any device. Any software developed with CrossBrowdy should be able to be used in any JavaScript compatible web client (including browser plug-in, add-on, extension, app...) which supports "document.getElementById". This framework allows any developer to manage easier many different things, such as audio (with Flash fallback, audio pool, etc.), canvas (with DHTML, VML, Flash or Silverlight fallbacks), screen, mouse, keyboard, gamepads, sockets (including PHP proxy fallback), XHR / AJAX (with PHP proxy for cross-domain requests), device sensors (compass / magnetometer, gyroscope, accelerometer, light sensor, proximity sensor...) and many more.

LayerFS is a RISC OS image filing system. A LayerFS directory constructs itself from several source directories, where objects in the 'lower' directories are overlaid by objects of the same name in the 'higher' directories.

Pluto is an email and newsgroup reader for the RISC OS operating system (see https://www.riscosopen.org/), developed by Jonathan Duddington from 1997 to 2004. It stores emails and news articles in Boxes, and they can be Listed, Viewed, Written, Spell checked, Replied to, Searched and even Spoken out loud! After Pluto was released under GPLv3 here on SourceForge in 2013, it has had many improvements. Pluto runs on any version of RISC OS later than v3.10, including RISC OS 5 computers such as the Raspberry Pi, BeagleBoard, IGEPv5, Iyonix, PandaBoard, Wandboard, PineA64 and Titanium as well as the older Risc PC and Archimedes series. From v3.16 onwards the RISC OS version of eSpeak is not included in the Pluto download, but separately in the Files espeak directory. The espeak project itself is on https://espeak.sourceforge.net/ but seems currently dormant. For full details of all updates since v3.06b, please see the Pluto Web Site on http://www.avisoft.f9.co.uk/pluto/
