The recent "1st place" video by panicorept doesn't feature Champion Edition. I don't know what the 3rd game is (it looks like some kind of hack of WW) but it's clearly not CE.

There is video on youtube, not labelled as a speedrun, but with what seems like a time of about 15:57, which would make it faster than the current 1st place time

I noticed in hocinehocine's 17.00 entry the timer doesn't start until the fight has started. The speedrun.com rules specify the timer should start at character select which would add 6 seconds to this time.
