how do you know when u finished charging a gameboy advance sp? When i am charging does de light turn orange?

Answer 1

when you are charging, the light will be orange.

the light turns OFF when the gameboy is fully charged.

i recommend only charging when you actually empty the gameboy of the charge - it will increase the life of your battery
-----
when playing, a full charge has a green light. when it's halfway empty of the charge, the light turns orange, and when it's 3/4 empty of charge, the light turns red

Answer 2

no, when it is done charging, it turns green. I hope i helped! good luck bro!
