Picked it up at the Goodwill today, it's the platinum one. Came with Super Mario Bros. Deluxe and a Mad Catz battery pack/grip. The batteries are toast in the battery grip, so some new ones will be soldered in, or I might just toss it and run without it. Although if I did that I would need a battery cover for it.
I honestly have never had the original Game Boy Advance, only the SP and the DS to play Advance games. I really like how comfortable it is, and the shoulder buttons are NICE. Seems to put off some really good sound too, not sure if the speakers are bigger or better than the SP or what.
Anyways, my only gripe is the lack of a back lit screen!! I plan on modding it so that it's lit. Can it be back-lit or do you have to put the lights in the corner of the screens? Has anyone ever done a full on LCD swap (with a new backlit screen)?
I personally feel that other than it not having a light, I like everything about it more than the other options for playing Advance games (other than the NGC adapter). Am I not alone in thinking that?
