There exist further TAS WIP parts of Sutte Hakkun by Kaizoman666, for the stages
5-1 to 5-10 (

6-1 to 6-10 (

7-1 to 7-10 (

These were originally parts of a Snes9x1.43 movie file, but (after having the movie file transfered to an lsnes file) by adding blank frames at appropriate places as necessary to resynchronise the WIP on lsnes, it was carried over to lsnes by me:

The WIP movie file (by Kaizoman666) actually continues somewhat further than what the videos show, and goes up to about halfway into 8-3.
It seems that there might be 2 versions of this game, (J) which is the version that's used, and (NP) which apparently stands for Nintendo Power.
In some stages, starting at 6-5, the permanent hopping (that is generally done throughout the stages to lower the movement/points counter shown at the top right of the screen in order to reduce waiting time at the end of every level) causes far more lag than the frames it'd cut off from the score countdown at the end, so this probably should be changed/adapted accordingly.
As comparison material, and for the remaining stages, this video of a WR speedrun might help:
