Hi there,
             I have modded my Gameboy Pocket with a white LED that has a 100ohm resistor built in (I could bypass it if I wanted). I am happy with the brightness as I dont want it to drain the batteries too much and I mostly play it outside so it isnt biverted.

My problem is that the brightness of the backlight varies quite a lot depending on the battery state and whether rechargable or non-rechargable. I have not had this problem with my DMG. The solder points are used were at the bottom of the gameboy in accordance with this tutorial :https://www.youtube.com/watch?v=i0PlML-q4Lo

I have since seen other tutorials that use points on the cartridge connectors. Does anyone know if the voltage regulation is better at these points? I am currently abroad and do not have access to test this for myself.

Any help would be appreciated.
