if you haven't tried it then try ityou can only toast the screen if you leave it at 0x3FF brightness for too long. if you accidently go from 1 to 0x3FF, you can safely go back to 1 by just overflowing the value a bit past 0x3FFwell... this thing isn't running in the background at all when you exit it :/ all this program does is abuse the fact that you can mess with sensitive GPU registers from userland; this is only a control panel of sorts for configuring the new3DS's color correction hardwaresorry, idk how to do that :/
