just out of curiosity, how did you do the port?
I think must have done the following (somewhat archelogical
1.carefully took the 68k code from the ST
2.adapted the graphic output and soundoutput.
3.adapted the controller input.
did you rewrite the original assembler routines for graphic output ?
or did you left it original and untouched and instead tranformed the ST buffer content into amiga bitplanes?
