I'm interested in programming a virtual machine, nothing as fancy as virtualbox or vmware, but something that can emulate a simple architecture, be it cisc or risc, say the Zilog, SPARC, MIPS, or 80686 architecture models.
I suppose by doing this it would be relatively simple to make an emulator of the same kind, I'm just interested in using this for experience more than anything else (being my first C project, I'd rather do this in C than in anything else).
