It's interesting that people are still playing this old game. I don't care if they keep their strategies to themselves, and I don't blame them for wanting to keep their WRs after they spent the time to figure out all the stuff on their own. If anyone wants to beat their scores, they'll have to be smarter and have better reflexes. That's the way it should be.
This is a bit of a tangent, but I think too many players these days simply spend their time memorizing the patterns of others rather than planning out their own unique strategies. I'm guilty of this too, of course, but there were times when I figured out things on my own. For example, when I first got my Futari BL PCB (when it was released in 2007), there were no videos, and I had to figure out stuff on my own. It was both challenging and satisfying - getting 855mil in Maniac mode with Reco (six months after the game's release) with my own strategies remains one of my proudest accomplishments. Oddly, no Westerner has beaten this score yet. Also my Pink Sweets PCB infinite lives 1CCs - I figured out all that stuff on my own and I'm proud of that too. I'm proud of what I did in Muchi Muchi Pork as well, as a lot of that I had to figure out on my own (especially the second loop stuff) due to a lack of vids to study.
In contrast I'm not nearly as proud of any of my Futari 1.5, Espgaluda (I/II) or Deathsmiles (I/II) scores as they were pretty much just a product of memorizing and copying as best as I could.
Anyway, just food for thought.
