Re: High Res Mode 2 by Paradox

I think I saw the problem, duringt he bottom border removal.
Before, bottom border, left border is removed with ;
MOVE.B D7,(A7)
NOP
NOP
MOVE.W D7,(A7)

But while removing bottom border, there's 1 NOP less, which means the switch back to med res happens 4 cycles earlier. Then, all your timings are 4 cycles earlier too for the rest of the bottom part.
In that case, the next write "MOVE.B D7,(A7)" will switch to hi res at the place where HSYNC signal is disabled, which means signal will remain enabled and this certainly cause the problems.

Can you try to add a additional NOP here, after the NOP ?
MOVE.B D7,(A7)
NOP
MOVE.W D7,(A7)

Of course, you will need to adjust your blitter timings to keep color aligned 4 cycles later.
