Ah ok and you programmed the GLUE/MMU chips to the metal? Great, just give me some hints about the problems with it.

Well i’ll put it this way. I recall creating copper bars much easier on the amiga using the copper. I think on the st there were 4 timers in the mfp68901 ( i think that was the chip ) which you had to manipulate (timer b iirc) to get copper bars going.

Also take the video register, on the st u could only set the video registers to a 256 byte boundary and no smooth scrolling at all - different atory on the amiga.
