The keys are configured for my N900 which has a spanish keyboard layout. I didn't have enough time to create a complicated config parser.

The numbers in the keys file are the keymap codes for:
Left
Right
Up
Down
o
x
triangle
square
Select
Start
L2
R2
L1
R2
Quit

The codes to enter you can find looking at http://www.koders.com/c/fidD9E5E78FD...FADE79933.aspx and converting the hex codes to decimal with a converter like http://www.xs4all.nl/~erikl/baseconv.html

I know its a bit complicated but the idea is to generate this keys file from the GUI later on.

The file chooser allows .img, .bin and .iso for now.

The ideal case would be to package it in a .deb that does the installation script as postinstall and checks for the python deps, but I didn't have time to figure that out yet. Any help is welcome.
