Done on MESEN, probably needs an official mod frame count but it should be around the time I submitted. This run was insane, I nailed early everything perfectly. There is a full second you can save on stage 5 by going for the chopper subpixel jump and also the lower route jump at the start of stage 5.

mod edit: 6:47.667 by my frame count, first frame of movement to first frame of screen transitioning
