Admittedly, it's still only an emulator and it's still in rather early development, but it will run many games with few to no compatibility issues, including the above pictured Zelda: Link's Awakening and Pokemon Red and Blue Versions.

The program works by converting a Nintendo Gameboy ROM into a calculator application. The save files are saved as application variables.

There are only two cons to this program:

The applications themselves are absolutely enormous, plus that doesn't include the save files. Depending on the game, you will only be able to fit one or two of them on a TI84+SE.

The other downside is that it requires an immense amount of RAM. Many calculators don't have enough to run it. Some games will be able to run on the 83+SE or on the 84+, but there aren't very many. Also, since TI has started changing the way the 84+SE calculators are made, many of the newer 84+SE calculators don't have enough RAM to run big games. The creator has noted that you can determine whether a calculator will have enough RAM by looking at the last letter in the serial number on the TI84+SE. If the letter is within the range of A-G, then it should work.

This is my favorite program that has become available for calculators. Even if you don't think that it's very great right now, it shows incredible potential. The developer is still working on it, too. In short, this is the best gaming program there is for a calculator.
