RPCemu
After having a chat with an old friend about RISC OS, I decided to hunt out my old ROMs and disk images and try out the RPCemu Linux port.
Actually its pretty good, certainly no VirtualRPC, but not bad, it runs RISC OS 4.02 just fine, I couldn’t get networking to work but did get HostFS to work (allows you to store RISC OS files on your plain Linux partition instead of using disk images).
