Hi guys, I've recently found an old gba sp, and want to mod it. Actually my first mod. Assuming I'll use a flashcart (still undecided whether to get an EZ DE or an Everdrive, help me to decide pls), what is the standard battery life with an IPS screen and a 950mah battery? Can I expect at least 6-7 hour of playing before put the gba on charge?
