I modded a GBA ^_^
(hexbear.net)
Installed an IPS LCD screen and an enhanced audio amp mod. (The audio mod was mostly to bypass a capacitor on the audio circuit that had gone bad)
Yes it does!
This one is done as far as mods go, I have thought about doing the rechargeable LiPo battery mod, but I see many people express a lot of concern about batteries exploding online, so I'm on the fence about it
I got a fresh aliexpress battery for my SP a while ago, but I end up playing my gba games on my powkiddy v90 instead
