Of course snes9x displays wrong values in RAM Watch, jumping doesn't go to 412 for one frame, it's slower most of the time... High-jumping isn't slower.
Saved 94 frames over my old shit run. Using several new tricks:
Jump boosting: After throwing something you'll be pushed 1,5px when landing.
Force quicker bonus countdown: Jumping, throwing on specific frames or alternating R/D (only useful on downslopes or before normal jumps). I got it down to 1, instead of 5.
