I asked the same thing a while back. I was under the impression that the hardware was similar. As I understand it, ARM2 code will run fine on a StrongARM for instance (although needing to turn off the cache if the code is self-modifying). Back in the day, there was the 'GameOn' utility - apart from the cache control (and better support for old-style screenmodes maybe?) I'm not sure what it did to achieve compatibility with many games - possibly patching them - but I think the differences weren't too significant - usually in these cases it's software that assumes a very specific environment that fail. It's possible that Arthur/RO2/RO3 would run on a Risc PC - don't know if anyone has tried it. It would be nice to have accurate emulation of older systems though as things like tech-demos are particularly sensitive to the configuration of the underlying (emulated) hardware.
