To be honest, I was shocked when I read this thread.
Honestly. Not because of a GBA question asked, but because of the many answers from our community.
To me you all sounded like "we are something better, if you can't help yourself, fuck off!" - which is definately not the helpful community I used to know.
Yes, this isn't a GBA board. Still, it is very valid asking a GBA question here - as this is the "Other Consoles" section.
To be honest, I would've asked such question rather here than in any GBA board.
Why? Simply because a most guys using a GBA have never opened it up, most users do only play their commercial games.
As the GP32 is a device for guys which aren't afraid modding their stuff, the chances finding a guy who knows a something about the GBA hardware is higher than in a GBA board.
Oh, and lubi: You didn't answer his question with google - as he never asked for a GBA forum but for fixing a broken LCD.
So guys, please think a bit about posting. If you don't know anything, just don't write anything. But don't act like you're more worthy than other guys...
