dms>My sincerest appologies... (dagnabbit my brain is becoming more like swiss cheese everyday!).
Yes you're right and I got it wrong. I wouldn't mind but after a brief trawl I found *me* asking the question does that mean a JIT (Just in time recompilation of ARM code) would be allowed. If not you *could* emulate an ARM to run RISC OS - just not translate the code to x86 to speed things up (your emulation would be a bit tardy but would work). Don't know if that ever got an answer.
So yes it does seem (I'd agree with your reading of it) that you can emulate ARM and use ROOL source in doing it.
