So in essence the ROOL software is Iyonx only unless it states otherwise. So for 80%? of the RISC OS market ROOL has no relevence.
Even if the foregoing is a simplistic statement and "some" of the ROOL software is usable on non-Iyonyx systems there are only a few clues as to any functionality improvements that may make it worth taking the risc [sic] of potentially hosing your system.
I apologise for what appears to be a ROOL bashing exercise - that was not intended. I applaud those people who are able to do this kind of work but weep when all these manhours are wasted for want of clear, meaningful guidance.
