Things You'll Need
Instructions
Download and install the connectivity software offered for free by Texas Instruments. A link to the file can be found in the Resources section. If your calculator came with a TI Connect software disc, you may have it already installed.
Follow the second link in the Resources section to download the Super Mario Brothers DX 4 file. Unzip the file by double-clicking it once it has downloaded. Save the contents to the location of your choice.
Power on your TI-84 and connect it to your computer using the TI connectivity cable that was included with your calculator. Alternatively, you can use a silver graphlink cable, available at electronics retailers.
Download the ION software and save all associated files to a new folder on your desktop. Open the folder and select all of the contents. Right-click and select "Send to TI device."
Locate the "PRGM" button near the top of the keypad and press it. A list of executable files will appear. Use the directional arrows to select the ION file and press "PRGM" again. This installs ION on your TI-84.
Create an archive folder for Super Mario Brothers by pressing the calculator's "2nd" key. In sequential order, press "+," "2" and "7." Locate the three ION files and use the directional pad to highlight one at a time. Press "Enter" to archive all three of them and form the folder.
Visit the destination folder for the Super Mario Brothers files. Select all, right-click the files, choose "Send to TI Device" and pick "Archive."
Access the game by pressing the "PRGM" key and opening the "Archive" folder.
