I'm currently working on a gbc frontlight mod, following this tutorial http://mikejmoffitt.com/wp/?p=70 I used red and green wire but you can use whatever colours you want. Pics (backlight frontlight from AGS-001 gba sp) 47 ohm resistors Install pictures Pry the screen away from the case. It is stuck down with glue so be careful not to use too much force. Cut away all the plastic highlighted here. Forgot to cut this bit of plastic out. Solder two wires to the metal contacts of the gba sp frontlight. The red one will be soldered to the switch as ground and the green one will be soldered to the resistor. (Red is - voltage and soldered to the bottom contact, green is + voltage and soldered to the top contact) To remove the lcd screen, I pushed up the two side tabs. Then I carefully removed the ribbon cable. Put the frontlight into the case like so. Place the lcd on top of the frontlight. Place the gbc board back into the case. Re-attach the lcd ribbon cable. Here is a pic of the mod so far. Solder the red wire to the switch like this. There are 4 pins here.Clip the ends off the resistor and solder to the top one. Then solder the green wire to the other end of the resistor. Put case back on. Before mod install After mod install edit: Frontlight, not backlight D: Edit edit: This was a triumph. I'm making a note here, huge success.
