ArcEm is a register level emulator of the Acorn Archimedes A4x0 system based around the ARM microprocessor. It is distributed with ARM Linux binaries and will boot ARM Linux and Acorn's RISC OS 3.1. It runs under X, Win32, and RISC OS. It is based on the release of the ARM emulator core by ARM Ltd, although this has been heavily modified for the emulation. It is a reasonably accurate register level emulation and as such should run pretty much anything.
