Hi all

Heh, well i've sussed out what was wrong with my code, the CLUT colour
retrieval was working properly, but I hadn't copied the right area of VRAM
to my buffer, doh!

I should have been copying from where my game graphics start, instead it was
copying a 16*8 block from the top left hand corner of VRAM.  And to make
matters worse, I forgot to allow for the size of the pixels in VRAM for
8-bit sprites - 8 bytes in VRAM in 256 colour mode represents 16 pixels!!


So when i've coded the routine and buzzed off it a bit, i'll knock together
another tutorial and put it on my site!

Cheers

Andy
