I did ponder linking to the parent.  Makes sense, I guess.

Agreed about the main RPCEmu page.  I liked the info on ROOL’s site
when I last saw it, and I like the idea that we can all edit their wiki.

Aso, I didn’t realise the page wasn’t Sprow’s.  Must be my laziness reading
the ‘last edit’ date.  :)

Ah yes, there is indeed an option.  Dunno how I missed that!
Thanks to David (and David!) for pointing that out too.

The reason I mentioned the VRAM was because a note somewhere said that
RISC OS 5 might show display corruption without it.

Also, I have found that with the ARM610 CPU emulation, RISC OS 5 is quite
crash-happy.  From a clean-boot, if I wiggle around a filter window, it will
crash with some silly ‘Filer may have gone wrong’.  SA110 is fine.

Has anyone else found this?

I’m sure I read somewhere that the SA110 emulation is the most extensively
used and so the most developed/mature.  I could be mis-remembering.

Good question.
