DSLite Brightness: Found the missing bit!

[wraggster]

Lick posted this on his site:

I found the bit in the UserSettings that stores the Nintendo DS Lite boot-up brightnesslevel. By reading/writing to this address, we can make the Lite boot-up with the desired brightnesslevel. Unless I’m slow, this hasn’t been done before.

Anyway, the bits are at the Language and Flags variable in the UserSettings. Bit 4 and Bit 5 will have to value of 0-3 (2 bits) indicating which brightnesslevel is stored.
(For read-only, libnds provides PersonalData->RESERVED3.)

Um, I don't get it. The DS already starts up at whatever brightness you had it set on when shut off.

What's really needed is an option where you can change the brightness during the game, like the PSP. I'm surprised Nintendo didn't put that in anyway. It's really frustrating when you go outside with your DS and you have to reset it and change the brightness so you can see the screen.
