- The problem with current emulators is, that there's only one
- documented bitmap format one may directly write to, the Amigas
- 8 bit planar format. With RTG there would be documented formats
- for 8 bit chunky, and at least 16 and 24 bit direct color too, and
- blitting between them would include automatic format conversion.
-
- Currently you can only use 8 bit planar bitmaps as source bitmaps
- or use "hacks" like WritePixelArray8().

- Sure. What counts is that it just happens, not the resulting quality
- or speed :-)
