betatester sent in a link to a sweet gba mod. this looks really cool especially for folks like me who bought a gba before the sp came out.
This is a mod of all mods for the GameBoy Advance. Essentially converting it into a game console with an ability to attach a joystick, output video to a TV or an RGB monitor, and provide power management to get around wasting those batteries.
The result is amazing and breathes new life into your GBA, even if you only decide to do the joystick mod.
so there you go — power adapter, joystick, tv output — it’s like 3 sweet gba hacks in one! i’m looking forward to trying this one out.
