Map fix for Zelda:TP?

[MandyDark2]

I really hate this part of game, both areas, Hyrule Field and Farone's Woods are sooooo slow.

I hope Dolphin Team can compile a version of emulator that can fix those kind of problems, even fix the FPS problem in some areas like Kakariko's Village and Ordon Village, in my case, i got in the last one, about 20-15 FPS, and it's totally frustrating
