This may be a bug but I'm wondering if it can be made into a feature:
On my n3ds, I have coded higher screen brightness values in luma - up to 170.
In my config.ini for open_agb_firm I have the default brightness set to 170 as well even though github says the max value is 142. When I start up a game, I can use X+DOWN (which normally lowers the brightness) to raise it to what I imagine is the 170 mark, making it brighter than normal. If I try to lower the brightness any further, it goes back to its original values and can't hit that high mark again until its rebooted. Any chance of programming in the higher brightness values permanently?
