RNF Quality Programs: LOTOPACK Readme:

I think that ti is rather self-explanitory on how to use these.
Here are the steps anyways.

1. Unzip this folder.
2. Send this file to your Ti-83 Plus OR Ti-84 Plus Calculator.
3. Ungroup the LOTOPACK Group [+]+[2nd]->[8]->[LEFT]->(Select LOTOPACK)->[2]
4. Good luck, my friend. YOU WILL NEED IT.

Happy Nerding
