Thanks, some useful info there.
I've noticed the memory saving function of Fblit seems to only work with newicon image data and not the regular icon data in Scalos. Do you know if that's the same on normal workbench systems?
For instance, on a 64 colour newicon system it offloads quite a bit to fastram.
However, on a 16 colour normal icon (WB 3.0-3.1) system nothing is offloaded to fastram.
