So what? It is v big but there is plenty of space on the
HIRes bitmaps are using version 3 of bitmaps (which specifies density and
other things). You cannot simply add a bigger bitmap at the end of a bitmap
family.
The very latest version of PilRC (2.9p5) supports HIRes bitmaps through the
BITMAPFAMILYEX keyword. Check it out.

Hi all, it's me again.
Right, I've taken a few decisions, firstly, I'm only going to use 8-bit
colour for all color platforms. For the game that I'm doing there is no need
for more colours than that anyway. This leads to question 1: "Are there any
devices that have some kind of colour support, bu

Using MemMove (just to copy the screen buffer to the screen) I'm at 43fps,
using FastBlit (with a couple of my own tweaks :) we're at 51fps. That's
significant enough for me. This is on an m

Thanx alot for this, just using your FastBlit to copy my screen buffer to

For fast memory copies, you should really NOT use MemMove.
First of all because it's a trap and you get the trap dispatcher overhead
everytime you call it. If you call it 20x for the 20 lines of each of your
sprites, it's significant.
Then because it's not optimized AT ALL. You can probably implem

FYI:
fullscreen 160x160 update = 128000 clocks @ 16Mhz = 125 fps
this means, if you are double buffering - you can get 62 fps.
on a 33Mhz unit - you can get 250 fps :) this is of cou
