Getting games on your Calculator.
PC to Calculator:
For this you need a TI Connect cable.
1) First download TI Connect software from
Here
Next download Mirage OS from
Here, follow the directions below to install Mirago OS and add more games
Don't have a pic with this one since I lost my TI Connect cable.
2) Next, find games/ applications you want from, my favorite sites are
www.calcgames.org and
www.ticalc.org. Download the games and extract if necessary (if it's a .rar file).
4) Now send the contents to the connected TI device, however right before you do this hit 2nd and the button in yellow saying Link, hit the
right arrow once and hit receive. As it says waiting, send the files to the calculator and the transfer will be done.
5) Usually the games show up under APPS.
Calculator to Calculator:
For this you need a calculator to calculator cord. The TI 84's support usb while 83's support I/O.
1) Hook up the cord between the two calculators.

2) On the one you are sending files from go to 2nd->LINK->PROGRAMS (Or APPS in some cases) and select the ones you
want by pressing enter. Then hit the right arrow and click transmit, but before doing so hit 2nd->LINK->RECEIVE on the the
other calculator.
3) Once the files are done, you are done!
Mario:

Pacman:
THis is also beneficial for different applications. My favorite one is the quadratic equation solver, where all you have to do is plug in A,B,C and you get an answer.
The games might not be much, but they've never failed to help me get through a boring class.
