here's a small status update:
- rework the wifi code, both wifi tx/rx are working (see patches below).
- compilation of thumb code, saves around ~200Kb (I'm still testing this).

I've been also reading about the new Nintendo's DSi,
which seems to run .nds files using the ak2i adapter,
if that's the case then the DS port will also run on the DSi.

The most important improvements of the DSi (AFAIK) are:
- more ram available (4 Mb to 14 Mb)
- faster wifi (around 11 Mpbs).
- bigger memory screens
- upper and lower touchscreens
- ...

PS: in the patches i've included a morse game i started playing with
when i saw that the wifi code required more skills than i had,
at that time it seemed the most feasible way of having wireless comms.

just to not repeat the same errors I made before,
I blindly assumed that the only docs about the wifi were DSwifi's sources.
And some time after I noticed that the wifi is also covered in the gbatek.txt

So: when in doubt check the gbatek.txt!

i've continued playing with morse.b, now works with data either text
or audio (pcm)
which can be listened/recorded from /dev/audio, it works in both
directions (encode/decode).
Moreover morse.b now comes with documentation in morse(1).

Future work which is still to explore includes some fun uses like:
comunications, remote control, ...

morse.b http://code.google.com/p/inferno-ds/source/browse/trunk/root/appl/nds/morse.b
morse(1) http://code.google.com/p/inferno-ds/source/browse/trunk/root/man/1/morse
