This should probably be in comp.sys.amiga.tech, but here goes,
If you allocate and store all your bitmaps in ram, you are going to
be using a bunch of memory. There is no way around that. If you want
speed, storing in RAM is the best way to go. After that, check the RKM
for uses of Dual Play field and SuperBitMap. I think there are specific
commands for doing scrolling.
