SFX Freezing on Gecko OS

[........]

I tried to load custom sfx on gecko os using the soundbank engine code but it froze my game on the strap loader screen. I placed all of the sawnd files in the right place. Help, please?

Did you make the .sawnd file yourself? If so, you probably violated a file size limit. Try to keep the replaced audio files' size equal to or below the original ones. Reducing the sample rate in an audio editor (like Audacity) is a good way to save a lot of space.
