I have 20 Mbytes of Fast RAM, 1 Mbyte of Chip RAM and a graphics board: Why does Personal Paint still use some of my precious Chip RAM?
Only Amiga makes it possible… Two crucial parts of the Amiga system require bitmap data to be stored in Chip RAM: the original (Agnus) blitter chip, and the Graphics library. Personal Paint uses both. By using its own virtual memory functions, Personal Paint limits the use of Chip RAM to the objects currently being processed (for example, graphics environments, brushes and animation frames other than the current one can be stored in Fast RAM, or even on disk). If you look at the documentation included with the program and with the blitter libraries available in the Download section, you will see that Personal Paint 7 can work without using Chip RAM for its bitmaps. This is done in two steps: first, a blitting library not using the Agnus blitter must be selected (turn off “Settings/Graphics/Amiga Blitter” in Personal Paint); second, all functions of the Graphics library which require Chip RAM must be replaced with compatible functions which can work on Fast RAM. The original Amiga gra
