Removed the 2 frame sacrifice and saved it up to 4-2 start by manipulating timer 0 to last boss death.
Side effect: 4-2 knife thrower is few frames slower, we have very bad position (spawns are at 0.5px distance, too much interrupts) and can't really manipulate it on the level (needs different subposes earlier).
Desyncs at 4-2 end. (84 Y pos is the required height, this time Ryu scratches 88 barely.)
