Twilight Princess Hyrule Field Speed Hack

[LuckyLittleSam]

Hi, I've been playing The legend of Zelda Twilight princess on the dolphin emulator for a while now and I'm tired of the lag when trying to pass through Hyrule filed. I'm well aware of the Speed hack, but I don't know where I'm supposed to find it. I can't find any ISO properties to change or .ini files to open. Could anyone please help me figure this out so I can enjoy the game without all the lag?
