My app 3DS Controller doesn't use the top screen at all, and only the bottom screen occasionally for the on screen keyboard functionality.

So, to conserve battery power, I would like to disable backlight. Is this possible?

Worked it out.

#ifndef REG_LCDBACKLIGHTMAIN
#define REG_LCDBACKLIGHTMAIN (u32)(0x1ED02240 - 0x1EB00000)
#endif

#ifndef REG_LCDBACKLIGHTSUB
#define REG_LCDBACKLIGHTSUB (u32)(0x1ED02A40 - 0x1EB00000)
#endif

static u32 brightnessMain;
static u32 brightnessSub;

void disableBacklight() {
u32 off = 0;

GSPGPU_ReadHWRegs(NULL, REG_LCDBACKLIGHTMAIN, &brightnessMain, 4);
GSPGPU_ReadHWRegs(NULL, REG_LCDBACKLIGHTSUB, &brightnessSub, 4);

GSPGPU_WriteHWRegs(NULL, REG_LCDBACKLIGHTMAIN, &off, 4);
GSPGPU_WriteHWRegs(NULL, REG_LCDBACKLIGHTSUB, &off, 4);
}

void enableBacklight() {
GSPGPU_WriteHWRegs(NULL, REG_LCDBACKLIGHTMAIN, &brightnessMain, 4);
GSPGPU_WriteHWRegs(NULL, REG_LCDBACKLIGHTSUB, &brightnessSub, 4);
}
