I'm trying to get MIDI into the GBA through the
serial interface. I've done lots of experimenting
with this serial port (cf.
http://hypermedia.loeil.org/playmobile/user/douglas/)
but getting MIDI in looks like it's going to be a
little uncomfortable. Has anyone already done
this? (I already know of all the GBC MIDI
projects -- pushpin & firestarter -- I'm
interested in a GBA-specific solution).

The main problem is that MIDI working at 31250
baud whereas the GBA supports only 9600, 38400,
57600, and 115200.

I was thinking of using the serial port in
General-Purpose mode, and trying to figure out
all the timing. This is cleaner than building a
PIC-based MIDI->UART converter, but I don't
really have any experience with General-Purpose
so I wanted to get someone's (anyone's?) opinion
on this matter before getting my hands dirty.
