The WAIT instructions will only wait for end of line, but ignore the VPOS. Something like $00df,$00fe? After writing to COLOR the next line has started and I can wait for end of line again. Very good idea! |
Yeah.

Ok. The only question here is whether the number of available memory cycles until DDFSTART are sufficient to load the pointers for all five bitplanes, write the COPJMP and COLOR.

It should fit if you only need to modify low 16-bit of bitplane pointers. If not, split copper list can be started 1 line earlier, wait for nearly end of next line and then do the split.
