I have a RasterOps 24bit card in my SE/30, and I'm quite
happy with it. I only have this problem:
I want to TRY and make an arcade game using 24bit color.
This involves blasting longs into memory. No problem, I
take baseAddr and rowBytes and do the appropriate
arithmetics, assign a long * and try to draw a line.
No go.
Maybe the wrong address ? Break in roms and check QuickDraw
draw the line. Right address.
Tweaking and trying for four hours.
No go.
Copying the memory-move instructions from QD into an asm
construct.
No go.
Obviously, there is something fishy going on. How can I copy
a long into screen memory and have it show as a dot ?
(PS: Screen memory for this card is mapped starting at FB002000)
