Quote from: andycadley on Today at 18:27Sorry - I think I may have muddled up everything by not explaining well. I meant that you can fit more sprites in mode 1.Quote from: sigh on Today at 17:08160*200*16 = ~16KQuote from: andycadley on Today at 16:29Then I have been completely wrong all this time!Quote from: sigh on Today at 15:36Was thinking that with the mode 1 graphics, you would have more graphics space for sprites?It doesn't really work like that, Mode 1 has twice the horizontal resolution and half the colours, so the end result is graphics take the same amount of memory to fill the same physical space
You could save memory by reducing the colour depth of stored graphics and converting them on the fly but that loses speed (and it doesn't really matter what the target Mode is at that point).
I thought a mode 0 sprite sheet that is 160x200 was 8kb and a mode 1 sprite sheet that is 320x200 was also 8kb?
320*200*4 = ~16K
You have to drop in colour depth or resolution to actually save memory.

Quote from: GUNHED on Today at 15:04Sorry, the GX4000 has only half the RAM compared to the CPC6128. Furthermore the CRTC RAM is 64 KB in both cases. ROM is another thing. The GX4000 itself has none.It doesn't work like that in practice.
