From here you will see a list of all the Gameboy games on your calculator and can play them by selecting one and pressing enter. On your calculator, hit the button, and select TIBOYCE by pressing enter. Send the converted ROMs to your calculator (there may be more than one file per ROM), again using TIConnect CE. Once you have found the Game Boy ROM(s) you would like to use (you can find them with a quick Google search), go to this website to convert them to a calculator-friendly format (alternatively, you can use the ROM converter program found in the file you downloaded). If you need help doing this, refer to the video above. Then, send them to your calculator using TI Connect CE.
