Not necessarily since the modules might in different order. But ARM7500
has some things the others don't but generally they are similar.

Err no, There is RISC OS 4.02 or 4.39 depending on version and of course
RISC OS 6 can be installed and you can switch between the 4 or 6 version,
I know cos I have it that way. Plus someone claims to have retro fitted
RISC OS 5 on VRPC DL somehow, but personally would not recommend it.

Are you forgetting this is a Windows program and not real hardware.
