I've emailed Mika and we briefly discussed this issue. It's not really that odd because the sound effects are stored in the WAV format, which is geared towards little-endian machines. I've taken a look at a couple of endian-safe .wav loading systems that I may be able to port over (I could find name if you'd like, I can't recall them off the top of my head...). I've also looked briefly at just writing a new loader from scratch, based on the WAV spec. It wouldn't take a real coder any time at all, but it'd probly take a rookie like me a couple dozen hours.
Anyways, between finals and my new summer coding job, I don't know that I'll be able to get down to writing code for this 'till the summer's over at least...
