Nintendo DS Lite VR1 / VR2 replacement

Hello everyone!

I recently got a working ds lite and a loose motherboard that came with no slot 1 and a missing VR1 potentiometer and a slightly messed up VR2 potentiomenter.

Since it has no slot 1, i was hoping to make a gameboy macro out of it. I tested the motherboard and it seems to turn on, but the screens stay black, i guess its because VR1 is missing. Anyone has any idea which potentiometer i can use to replace the missing one?

Thanks in advance for any help.
