What is ArcEm?

ArcEm is a Acorn A400 hardware emulator that is highly portable, it currently runs on Unix (X Windows), Microsoft Windows, Mac OS X, the GP2X handheld, RISC OS and Amiga OS 4. As it's a hardware emulator it's capable of running multiple operating systems including RISC OS 3.10 and ARM Linux. If you're interested in helping out on the project, check out the developer page.

12 April 2006 - ArcEm isn't dead!

Contrary to appearances the ArcEm project is alive and well, over the past 18 months many bug fixes and enhancements have been made, including work such as HostFS, Sound support and the ports to GP2X and Amiga. See the features list below. We're preparing for a formal release of this work, but in the meantime feel free to try out a build from CVS, you won't regret it.
