I have tried the same test here.

VRPC on XP OS6.06 4516921
RPCemu 0.7 OS4.04 4940326

RPCemu is from the website http://b-em.bbcmicro.com/arculator/

RPCemu, OS4.04, was unstable on XP here, stiffing itself during copies.

Just to prove it is impossible to prove anything, I tried bogomips, the
UnixLib command line tool, I just double clicked on it.

VRPC on XP 216
RPCemu 0.7 54

I do have RPCemu running on Vista but is is missing some keystrokes
and neither does it survive hibernation, VRPC also fails in the same
ways here.

The next job is to try the Linux version.
