Also, you would be sattisfied with the narrowband decoding because the 
GBA sound quality isn't very good, however, that depends greatly on what 
you're going to do with speex on a GBA.... (an RPG with audio dialogs? 
;-)) also, using a DSP in a GBA Cartridge sounds like overkill to me, 
however, that depends greatly on what are you developing and what's your 
target audience....
