EDIT: Here's the info I got so far: There's 16 screws on a GBA SP, 7 screws from the outside, 9 from the inside. From the outside, there's FOUR 6.45mm triwing, TWO 4.6mm also triwing screws and ONE 4mm short phillips screw that holds the battery cover. From the inside, there's THREE 4mm long phillips screws holding the mobo in place.

Advice; - Try a different charging cable. - Try putting in a new battery, or try with someone else’s battery first to see if their battery will work in your GBA SP. Then you’ll know for-sure that you just need a cheap battery replacement bought online. As an aside you only loosen, but not remove the screw from the lid since it's retained on the inside with a little ring. Sorry to barge in, but I just got an AGS-001 Cobalt Blue, and wanted to replace the battery. Same deal, screw was stripped. I ended up just prying the cover open, and turning it to get it off.
