Theme Editor

A very nice, simple program made by Levak from Ti-Planet.

What theme editor lets you do is edit the theme of your calculator, allowing for you to customize the colors of the homescreen, document browser, etc. This does require ndless 3.1.

Game Boy Advance Emulator

Finally, after a long wait Calc84Maniac from has released his gpSP-Nspire, allowing you to play all those great Game Boy Advance games on your TiNspire! This requires ndless and another program called Nover if you want your calc to perform more effeciently.

First, install ndless 3.1. Second, download gpsp-nspire. It’s optional to download Nover to increase your calc’s speed by overclocking it. Third, download some GBA ROMs.

Now in your calculator, make a folder within your ndless folder called GBA Games, or whatever you want it called. Now send over game_config.tns, gpsp_launcher.tns, gpsp_resources.tns. Afterwards, acquire the BIOS file of a Gameboy Advance. Then, rename the file to exactly this: gba_bios.bin.tns.

Note: There are two common BIOS files that can be found. One is the worldwide used BIOS and the other is a prototype. If you use the prototype you will be given a warning and be asked if you are sure if you want to continue. This BIOS will not allow some games to function properly and may even ruin your calculator.

Furthermore, after downloading some ROMs, rename the ROM to [game].gba.tns. Now send the file to the folder that contains gpsp_launcher.tns. Unlike the GBC Emulator, you can search folders for games, so you don’t necessarily need to save the game file to the file containing the launcher. Finally, run the launcher and nonchalantly play while everyone thinks you are doing math.

The first program, ndless!

The first program I’ve decided to post about is one for the Ti Nspire family. It’s called ndless, and can be found here at the developers blog or here at What it does is it allows third party access to your nspire, allowing you to code in C or ASM on the calculator!

Firstly, download the latest version of ndless and make sure it’s compatible with your OS. If you have OS 3.2 or greater, go here to see how to fix that. Next, create a folder on your calculator called ndless and drag ndless_resources.tns and ndless.cfg.tns into it. Now, drag your corresponding OS to the calculator. After transfer, the installation bar won’t fill up all the way. That is completely normal. If everything goes as planned, on your calculator will be a small message saying you’ve installed ndless!

Ndless files/abilities


If you create a folder inside your ndless folder called startup, whatever program inside will run on boot.


Allows you to change settings for various ndless programs. To edit it, rename it with the extension .txt


Will uninstall ndless. Don’t touch if you don’t want this to happen. DO NOT DELETE WHILE NDLESS IS INSTALLED.

ndless SDK

Write programs for ndless with ndless C available through this dev kit! Allows you to test and build your own programs to be converted into .tns format for the nspire.
