Overview

Fuming! PSP Go trigger buttons are stuck! Playing God of War, press L to block but Kratos just stupidly takes damage; playing Ridge Racer, press R for nitro boost but car crawls like a snail! Now trigger buttons won't spring back after pressing, have to dig them out with fingernails! What's worse, sometimes they auto-fire continuously, character twitches like having a seizure! Should I glue them shut? No way! Today I must give my PSP Go 'sensitive triggers' and restore its shooting thrill!
