A dynamic recompiler is being developed and an early version is in SVN. It presently only works on x86 machines (both 32 and 64 bit), emulating a StrongARM in RISC OS 3.7, 4.02 and 4.39. It needs more testing, but can run RISC OS and the majority of applications at around twice the speed of the interpreter.

RPCEmu - Open Source RiscPC Emulator

riscos.info maintains the source repository for RPCEmu, developed by Tom Walker. Peter Naulls did the port to Linux. Chris Williams did the Mac OS X PPC port. RPCEmu is an dynamic recompiling (JIT) emulator of Acorn RiscPC-class hardware. It includes working emulation of ARM6, ARM7 and StrongARM cores, IDE and Floppy emulation, VIDC20 and IOMD chipset emulation, and other features.

Present limitations:

  • No access to host floppy drives
  • No network access.
  • Unable to run non-RISC OS operating systems correctly (eg Linux)

Developer help wanted

In case you are a developer and want to spend some time on RPCEmu project, this is a non-exhaustive list of ideas to get you inspired:

  • It would be a good thing to have Windows, Linux and Mac OS X ports unified.
  • Address its emulation limitations (like host drive and network access)
  • Test the dynamic recompiler

Make sure you involve Tom Walker when doing development on RPCEmu.
