This certainly used to be a problem, as I describe here
  http://www.riscos.info/pipermail/rpcemu/2014-January/002193.html
but it looks like those changes (or something similar) got added to RPCEmu's
sources on 21-Oct-2014. 

Both ARM610 and ARM710 seem to boot OK for me (Windows, recompiler, 0.8.12)
with RISC OS 5.22 and wiggling filer windows also does nothing exciting.

Does the interpreter version of RPCEmu do something different?
