------------------------------------------------------------------------------
This lib is a raw porting of tonclib library for gba (you can find it at
http://user.chem.tue.nl/jakvijn/index.htm).
As this is a direct port from c, I'm pretty sure that something could not work
as you expect. I am even more sure that this code could be written better, so
if you think that I have made some mistakes or you have some better
implemented functions, let me know [francky74 (at) gmail (dot) com]
Enjoy!
