Tired of the same old games on your TI-Nspire? Want additional functionality for your calculator, or to program in C or Python directly on your calculator? Well, Ndless is the perfect application for you!


What is Ndless?

Ndless is a jailbreaking application that enables your TI-Nspire calculator to run native programs, such as C, JavaScript, Python, and ARM assembly programs. In addition, Ndless will vastly expand your calculator's functionality, from PDF viewers
to Linux to Gameboy Advance emulators. To see a complete list of Ndless Apps, visit https://ndless-apps.org/.


Downloading Ndless

Before You Start
If installed properly, Ndless should not damage your calculator. However, given the potential risks, it's recommended that you back up your calculator's files.
Also, you will need to download the TI-Nspire Computer Link software to transfer files to your calculator.

Check Your OS
To check your operating system version, press [ON] - [5] - [4]. When you transfer the Ndless files to your calculator, make sure you send the correct files for your calculator's OS!



Preparation
1. Download Ndless and extract the archived content.
2. On your calculator, create a top-level folder called “ndless”.
3. In this folder, transfer the ndless_resources.tns file and the ndless_installer_X.X.X.tns file for your OS from the extracted archive to your calculator using the TI-Nspire Computer Link.

Note: You can also transfer the ndless.cfg.tns file to handle extensions association.



Installation
Now open the ndless_installer_X.X.X.tns file. You may be prompted to press [Ctrl] - [W] to complete the installation. After about 30 seconds, a message should be displayed in the top left corner of the home screen. You have now successfully installed Ndless!



Feel free to leave a comment if you experience any problems!

Note: To uninstall Ndless, open the ndless_resources.tns file or reboot your calculator.
