Two days ago there has been a change in the OSX port of RPCEmu
. Since that is only a Mercurial repository of the sources I did a build of the latest version for those few who might be interested in Acorn RiscPC emulation.
I can't really provide much help with the binary because I hardly played with it, and for some reason still can't get disc images to work...
Anyway, if you want to check it out by yourself, you can download it here
