I saved 42 frames on blk 4-03 Boss using whip instead of boomerang subweapon, as well a small lag reduction.
6230 frames faster. NOTE: I returned to Stage 9 to fix 13 frames. NOTE 2: Input ends much different than published run.
Stages 7, 8, 9 & 10 finished! 3402 frames (approximately 56 seconds) faster than published run. NOTE: Fireballs collected in order to save time on the last boss later.
Found a glitch on Stage 4-2 a more than a year ago: It's possible to jump immediately when this stage starts. Jump, and fall down inside the wall. It works only with stimpy, I think. A savestate is required to watch this movie: http://tasvideos.org/userfiles/info/36227256741808552
