The title says it all, no matter what value I write to that register in order to change the contrast or luminance it doesn't do anything. The (16-bit) register is at address 0x2934, and I used rlyeh's line from gp2x_video_setluminance() (after disobfuscating the constants, why on Earth does he write "0x1253+2041-0x1a44" instead of "8" ??), and really, nothing happens..
How come, I mean, why not? Or does it work for someone?
