I'll release an extremely early build just to get feedback.
Yes, this is extremely early. Does not support sending programs to emulator, or savestates. Only emulates a TI83.

How to use:
* First append a TI83 rom image to the end of the .gba file, using something like copy /b ti83emu.gba + ti83.rom ti83emu_rom.gba
Keys:
SELECT: Toggle keyboard overlay
Keys (keyboard visible)
* Arrows: Move cursor
* (right now cursor is not displayed over arrow keys, just move it away a few times)
* A: Press that key
* B: Quick Keys
* Start: ENTER
* L: Alpha
* R: 2nd
Quick Keys: (Hold down B while keyboard visible)
* A: ENTER
* Arrow Keys: Arrow Keys
* (other keys same as keyboard visible)
Fullscreen Keys:

* A: 2nd
