is it here ? https://codeberg.org/ahchay/NEOTYPE.ngp/...ain/main.c (multiplexing)
you mean hblank ?
I would recommend to call the hbl only every 8 lines and do the 'cut' at line 80 or 72, not really half but quite near
(or every 4 lines to get 76...)
and also hbl in pure asm to avoid all the extra stuff added (push & pop), it may help a lot
see discussion here: https://forum.freeplaytech.com/showthrea...9#pid10139
and in the last messages of the thread: "So I set the TREG0 interval to 9 and have events at RAS_Y of 8, 62 and 98."
