TI SP

[Quickstart3700]

When math meets gaming...
It's basically a Gba sp inside TI 84. All the normal buttons function as gba buttons with a as 2nd, alpha for b, etc.. It's not the first to be made but I think it's still cool.
And for the pictures:

Where's the speaker located?

I'm also curious about the unused buttons. Are they immobile, or can they be pressed down? Overall, it's always awesome seeing one of these, because I can imagine a person just spending hours a day in school on this.

I decided not to include a speaker cause I didn't feel like it. The'res a headphone jack though, so that fixes the sound problem. And yeah, I didn't think I was gonna use this in school when I made it but obviously I was wrong
