As I said on drobe, there's no reason RPCemu can't emulate ARMv5. Certainly if
it's just the one instruction. Might put that in today actually, see if I can
get !Draw running.

Yes, it's hardcoded to a specific machine. Hence why changing the amount of
memory in RPCemu does absolutely nothing - it's probably based on an A7000 with
an 8mb SIMM (loading the ROM into the motherboard-based 4mb?). Probably an
easier target to aim for than a RiscPC at present.

Yes, it's very much unfinished! Which makes me wonder how much support is worth
doing for it at the moment - at least HostFS and the mousehack need changes to
be compatible, but is it worth waiting for a more complete ROM image?
