I got it working! Here's what you have to do:
1. Download ION from
here.
2. Follow the instructions for installation (included in the ion.txt file when you download ION).
3. Send Mario.8xp and a few of the levels to your calculator, but don't archive them.
4. Run program A.
5. Run program Mario.
Let me know if that works for you. It worked fine for me, but there may be some compatibility issues with TI-84s.
