Syncs up to 6-1 start.
This WIP includes previous (v2) slot4 change on 5-2 last screen. Comparison to WIP136v1:
- 1 frame faster 5-3 2nd screen (to dodge shuriken)
- 2 frames faster 5-3 3rd screen by better positioning at the first few enemies
This way knife bitch is OK. Lost frames recovered, but I want to make sure that all screens from 5-2 to 5-3 is perfect.
