Hi David
It would help if you could confirm the version of RPCEmu (0.8.11,
presumably?), RISC OS and Windows you are using. Here I'm using
0.8.11. Recompiler mode, running 5.20 on Windows7 64-bit, with no
speed problems (ROmark shows approx. 610,000 MIPs). The processor is a
3.4GHz i7 quad-core. I also have an 1.5GHz Atom-powered XP laptop on
which the same RPCEmu setup gives a ROmark score of 205,000 MIPs
(approx. 115% of a S/ARM RPC, which seems reasonable).

Amen to that! But it isn't just a question of configuring RPCEmu,
presumably: as I understand it, before RPCEmu can connect with the
outside world, Windows has to be configured to allow this (i.e,
setting up the network bridge). Automating /that/ procedure for all
the different flavours of Windows would be quite some task, I imagine.
