RPCEmu has been ported to the Mac OS X platform, allowing RISC OS 4 to run alongside Apple's shiny desktop. An experimental port of the open source RiscPC emulator was checked into its source code repository over the weekend after the emulator was adapted to run on Apple computers that use PowerPC processors. A build for new Apple machines shipping with Intel CPUs is also possible, although this has not been committed yet.
The port can run RISC OS 4 and 3.7 with mouse and keyboard support. The emulation of IDE hard discs and higher resolutions needs further testing, and the user interface needs more work. The emulator manages around 5 MIPS on a modest 800MHz G4 iBook - which makes the desktop fairly usable.
The source code for the port can be found in the riscos.info svn repository from the links below, in branches/ppcmacport. It is hoped when the application is tidied up, it can be merged with the mainstream RPCEmu source code. A full release is expected once the port has been completed and rolled into an Apple application package. Adept Apple users, with PowerPC and Intel powered computers, are welcome to ask for an experimental build to provide feedback.
Originally developed by Tom Walker for Windows, RPCEmu was later ported to a PocketPC PDA and to the Linux platform.
