Recently bought a Gameboy Advance SP from someone. It's in alright condition. The thing is, the L and R trigger buttons are a bit used up. You hear very little "Click" sound when you press on them. I guess this is normal after years of use. I was wandering if there was a way to fix and "fresh up" the trigger buttons. The battery is another option I'm looking at to replace. Also I would like to know if there is any online stores that still sell EZ-Flash IV with micro SD support. Thanks Summery: -Bought a GBA SP - Trigger buttons ("L" and "R" are a bit worn).
