NintendoDS: Kit de desarrollo (devkitpro.sh)

Hemos instalado el devkitpro, un kit de desarrollo para la Nintendo DS que se basa en la librería PA_lib.

No sé si al final saldrá algo bueno de todo ésto, pero para quien lo quiera intentar aquí queda un bash script que lo hace todo sin apenas esfuerzo, devkitpro.sh (no es de cosecha propia, pero tampoco es sencillo de encontrar sin registro previo): 
#!/bin/bash

Resolvemos los requisitos previos para que el script funcione correctamente (wine, p7zip, unzip y unrar), luego lo ejecutamos, hacemos un backup de nuestro .bashrc por si las moscas y le agregamos las lineas que siguen: 
$ sudo apt-get install wine p7zip unzip unrar
$ ./devkitpro.sh
[...]
$ cp ~/.bashrc ~/.bashrc.backup
$ cat .bashrc
[...]
# PALIB
export DEVKITPRO=/home/usuario/devkitpro
export DEVKITARM=$DEVKITPRO/devkitARM
export PAPATH=$DEVKITPRO/PAlib
alias nds='wine /home/usuario/devkitpro/nocashgba/NO\$GBA.EXE'
$ source ~/.bashrc
Y ya podremos entrar en el directorio PAlibExamples/Transitions/BgTransUpDown (por ejemplo) y hacer un make para ver que uno de los ejemplos funciona perfectamente. Al compilar nos van a aparecer 2 ficheros, el .nds y el .gba; cargamos el adecuado en el simulador y comprobamos su funcionamiento.
