CrossBun is a crossword puzzle program for the TI-84 Plus CE graphing calculator. It's heavily inspired by Crosshare.
To install, transfer CROSSBUN.8xp and clibs.8xg from this repo to the calculator using TI-Connect CE or TiLP.
On newer calculators (OS 5.5 and above), you'll need to use arTIfiCE and optionally a shell like Cesium to run the program.
You'll also need to transfer at least one .8xv file containing crossword puzzles in order to use the program. These can be created from .puz files using the convert.py script.

You'll also need to install its dependencies, e.g. pip install puzpy bitstring tivars.
Then, you can run it like so: python convert.py --title "My pack title" --description "Pack description input1.puz input2.put input3.puz MYPACK.8xv.
