About

What is Pyromaniac?

RISC OS Pyromaniac is an alternative implementation of RISC OS for non-ARM systems. It provides a semi-hosting system within which RISC OS binaries (utility, absolute, and modules) may be loaded and run, within an operating system environment which matches RISC OS Classic very closely.

RISC OS Pyromaniac is:

A command line and graphical version of RISC OS.
A RISC OS which runs 32bit ARM binaries, on Windows, macOS, or Linux.
A reimplementation, which uses none of the code that went before.
Focused on being able to test software and diagnose issues more easily.

A presentation about RISC OS Pyromaniac was given to the RISC OS User Group Of London in November 2020, and can be found on YouTube.

Where to find it?

Pyromaniac is not currently distributed.

A demonstration shell server can be found at shell.riscos.online.

It powers the RISC OS build server JFPatch-as-a-service.
