Low speed in Zelda: Skyward Sword

[Dilute]

Hey There,
I'm playing The Legend of Zelda: Skyward Sword on the Dolphin build 3.5-367 and using a Real Wiimote + Motion Plus, and I've been having speed issues in the game. The game runs at around 35% of speed, which is really annoying. All the controls and stuff seems fine. And suggestions for a newer version? Or some fix?
My PC specs:
4.0 GB Ram
Processor: Intel Core i5 at 3.5 Ghz

Also as a side question, Twilight Princess also tends to slow down a bit in Hyrule Field, thus running at 50% of speed. ZTP hack under properties is enabled. Any known fix?

Thanks in advance
