Hacking Sonic Colours(Pal) Freezes on Act 3 of first level

[maceds]

I used USB loader GX with the latest Cios and the game played smoothly until i got to the 3rd Act of Tropical Island. The level wont load ,the music stops and the screen goes black after about 10 seconds. After a few tries, I started a new game and used Gamma r9 to load the game this time and nothing changed? Is there a fix for this?
