There’s a number of options out there for running RISC OS on non-ARM hardware. The most popular and widely used solutions are:
- RPCEmu – If you don’t want to spend any money, then emulation will be the best place to start in the form of RPCEmu. Compatible with legacy RISC OS versions (3.xx, 4.xx, 6.xx) as well as RISC OS 5. Although be aware that as brilliant as it is, RPCEmu is not yet fully representative of a complete RISC OS system – there are still some minor shortfalls that are not present in Virtual Acorn and native systems.
- Virtual Acorn – This is the most stable and authentic way of properly emulation a legacy 26-bit RISC OS system upto a StrongARM RiscPC. Compatible with Windows and OS X operating systems, Virtual RPC is only compatible RISC OS Ltd’s 26-bit variant of the operating system and is not compatible with RISC OS 5. Perfect for running older software. Ships with RISC OS 4.02 or 4.39 Adjust, compatible with RISC OS 6.
