I know iprefs use the ruddy useless things (datatypes) I was meaning for viewing GFX or playing audio, I prefer to use a dedicated util for such things.
I've never read much of the docs for MorphOS and can't tell you which versions I tried as I deleted them all a long time ago, yep still no RTG board.
PowerUP MorphOS has always required a RTG card. I don't know what you've tried but it doesn't sound you have been running MorphOS.
And after reading the thread a bit, indeed you weren't. Yes, indeed WarpUP sucked.
