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,
Secondly, I am going to support 320x320 on Sony devices.
Thanx to the guys that pointed this out to me, even if it
means that I have been introduced to a whole new world of
pain... :) In truth the Sony stuff hasn't been that bad at
all. But I have a question about that too (2) What is

Ok, I've had a go at doing this anyway, and whenever I include a 320x320

problem. But why can't I load the prc, is there some maximum size limit that
I'm breaking?

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.

Is WinGetDisplayExtent the best way to detect this then? If I get a ROM for

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

somthing similar for drawing my bitmaps, I will probably restrict them to
multiples of 16 in width and horizontal position to save on shifting.
