I have two GBA SPs, both the old one with the backlit (not frontlit) screen. One of them is in much better condition than the other, except for the fact that the screen is shattered. It still plays games, and I can hear the sound through the speaker, just the screen doesn't show anything because it's shattered. The other one has a screen that works fine, but it's not in as good condition. If I got a triwing screwdriver, would it be hard to take the working screen and put it in the other GBA?
