Hee hee. That's true. One thing I was thinking of, would it be possible to
do something like, BPPCFix to remove the ROM layers.library and patch with a
PPC byte for byte compatible version? Course, then intuition would best be
recoded. Just an idea I had that may work. Perhaps even a totally re programmed
soft-kickstart for ppc which was soft kicked would work. But then there is
a *lot* of work involved in that... :)

Well I have been using Frogger (just registred that and SoftCinema today :))
in 8bit colour, on its own screen using a standard MPEG-1 res, which is 358x288
or something. I then use a simple 8Bit AHI player (unit #1), allowing for a
fair share of *68K* CPU time. Like that, I have easily got 25fps with about
1-2 frames being skipped - still it is a enormous jump from 040 speed. I gave
up trying frogger on the 040! :)) Plus - no broken audio and its all in sync.

Excellent, I'd love to see that. Whether I have my BVision this summer is doubtful
since I want to buy more software now I'm close to having my dream Amiga (something
I always wanted since my very first own Amiga, an A500+) I may as well use what
I have got and not wait for what I will have. I'll probably attempt to get
a BVision at WOA if that happens if the truth be known. :) It's not as if I'm
w/o a gfx. card anyway :))
So I think I'll take you up on your offer... :)

I'll download that tonight :)

Is the X interface code seperate from the actual player? Just I installed VBCC
for PuP and WOS yesterday and had a go at convetrting some of my old 68K code,
which was not *that* optimised - now the speed was quite something.... :)
Tell you what e-mail me it and I'll take a look, I wonder how I'm gonna juggle
three big projects.... ;) I guess I'd need to use Ixemul.library a lot though...
To start with anyway :)
All the best,
Nick.
