Glad to see the flashing help bar was fixed!
This is an issue for r06d, I haven't tested in r06e as I accidentally overrode my save (sorry, it took me probably an hour to get past this mini-game and I was a bit tilted by the end).
I had an issue with doing the dolphin mini-game. No matter where I stood I couldn't land on the bar (and I tried the normal whistle twice without moving). After turning off and on multiple options it was fixed by setting:
New_Translation = n
After this I noticed that I was landing in a different place. A bit further south-east to where I should have on the 1st jump. Though even trying to correct for this, I couldn't land on the bar.
