I recently got a hold of two Wonderswans and decided I wanted to front light at least one of them. After some research I found this screen. The screen seems to be the proper dimension for front lighting the wonderswan, and it was on sale for $3! So I grabbed four of them (in retrospect I should have gotten like 20 of them).
They came yesterday and I tore the thing apart and started off on frontlighting it. This will serve as somewhat of a guide for doing this.
First we start with the donor screen.
