16 / 64 colors , ressources and name

Unfortunately, our resource system only disambiguates devices based on screen shape and screen resolution. If you want to do something more than that, you'll have to look into using jungles. You shouldn't have too much trouble adding a per-device configuration that references a specific file/folder for additional resources (basically one line per device).

ok many thanks, I've never dealed with jungle, I have to look into it...

I hope the programmers guide is clear enought, it could be great if someone has an exemple of jungle file.
