Re: [Rpcemu] Emulate other ARM processors?

It's strange that Acorn were...at least in some people's opinion - big on backwards compatibility - but compared to the PC world, they didn't seem to do it very well.
Regarding Arculator/RPCEmu, I don't know, but looking at http://b-em.bbcmicro.com/arculator/ V0.1 of Arculator came out before V0.1 (or any version) of RPCEmu.

It's a large amount of work for archimedes support, of which the ARM is
the relatively easy bit.

I've considered it, but it's a long long way from happening anytime soon.

I think it might have been the other way round, though I'm not sure. They
both shared a large chunk of code.

In general, stick to Arculator, if it does what you want it too.
