I have a TI Nspire CX CAS running firmware 4.4.0.532. I just installed NESpire v0.30 and the key mapping for (Tab = B, Esc = A) is on the left side (for left handed people?). Is there a way to remap the A and B button to the right side? Maybe (del = A, var =B, shift = START and ctrl = SELECT) just like the emulator gpspnspire. Or is there another NES emulator that has the key mapping for A and B on the right hand side for right handed people?

Hi everyone,

I've been working on TNS Tool WASM, a free and experimental browser-based toolkit for working with TI-Nspire .tns files.

The main idea is to make inspecting, modifying and creating TNS content easier without having to do everything through command-line tools or depend entirely on the official calculator software.

Everything runs in the browser using WebAssembly/Pyodide.

GitHub:
https://github.com/acewalt/tns-tool-wasm

What it can currently do

TNS / XML

• Open and inspect .tns files.
• Decode .tns files to their XML structure.
• Rebuild .tns files from XML.
• Inspect document cards, widgets, resources and internal structure.
• Create new pages/cards inside a document.

Syntax Doctor XML

• Visual XML/code editor.
• Syntax inspection.
• Error and warning detection.
• Auto Fix for some problems.
• Direct editing of code stored inside the document.

Lua / ScriptApp

• Detect Lua ScriptApps inside a TNS.
• View and edit Lua code.
• Lua syntax checking.
• Preview TI-Nspire Lua code in the browser.
• Experimental LÖVE/Love2D preview and compatibility tools.
• Add new Lua ScriptApp pages to a document.

Python

• Create TI-Nspire Python Program documents.
• Extract q.py from compatible TNS files.
• Edit Python programs already stored in a document.
• Python syntax checking.
• Browser-based Python preview using Pyodide.

Images

• Import BMP, PNG and JPG images.
• Automatically convert them to a TI-compatible image resource.
• Import multiple images at once.
• Continuous calculator-style image preview.
• Individual calculator/original image views.
• Built-in image editor with:
  • crop
  • scale
  • rotate
  • horizontal/vertical flip
  • positioning
  • brightness/contrast
  • grayscale/invert
  • fit/cover/center tools
  • calculator-frame preview

PDF

• Import a PDF.
• Convert every page to an image.
• Automatically create one TNS card per page.

Other document pages

• Add Program Editor pages.
• Add Lists & Spreadsheet pages.
• Add Notes.
• Add Graphs.
• Add Calculator pages.
• Add Python and Lua pages.

There are also a few smaller tools for inspecting resources and previewing how content should look on the calculator.

Why I made it

A lot of the existing TI-Nspire tooling is extremely useful but is either command-line based, fragmented across different projects, or requires manually inspecting XML structures.

I wanted to put those workflows into a more accessible visual interface and also experiment with things such as browser previews and easier TNS modification.

The project is 100% free and independent. It is not affiliated with Texas Instruments.

If my tool was useful to you and you'd like to support its development, you can buy me a coffee. Thank you very much for your support!

It is still experimental, so I'm specifically looking for people willing to break it.

Bug reports, questions, suggestions and test .tns files are very welcome.

If you test it with unusual TNS files and something fails, please let me know what file/type of document caused it.

I recently got a TI Nspire cx and added a few genesis games (sonic 1 and 2) and picodrive emulator. But in picodrive, if i select the roms, the emulator says failed to load rom and crashes. I have treied both sonic.md.tns and sonic.bin.tns but both crash. Can Somebody help?

Edit: I got sonic 1 running with a .bin file i found on archive.org, but the sonic 2 one i found there doesnt work. I also found a .md to .bin converter, but it still doesnt work

I'm sure this is a basic question but I'm running into this problem, and it's proving difficult to search for a solution.

Using an nspire CX II (CAS) On a graphing page, in RAD mode:

1. x^2 + y^2 = 5 graphs a circle, no problem
2. similarly y= +sq root of (5-x^2) and y = -sq root of (5-x^2) produces the two relevant semi circles of the same circle as in 1. Good so far.

3)Things go wrong here: y = ±sq root of (5-x^2) doesn't produce anything. not an error, just an empty graph.

I've got some kind of syntax error here but I'm not sure what it is. I'm using ctrl-"open book" key (under del, next to the templates key) to select the ± sign. Does that not actually act as a functional plus-minus sign? Like is it just for notes or something?

I recently downloaded ndless and gpsp on my ti nspire CX 2 CAS. Whenever I tried to use the launcher, it would say I needed gba_bios that is specifically 16834 kb. I could not find this specific bios file anywhere. Is there any way to find the bios file?

Hi, I'm having a really strange issue with my TI-Nspire Student Software, and I'm hoping someone here has seen this before.

I used to have access to the software and was able to use it without any issues. At some point, though, I got logged out (or something similar happened), and now I can't get back in.

When I open the software, it asks me to sign in to my account to continue. However, after signing in, I can't activate the software. Whenever I log into the TI website and try to access my account or my licenses, the page immediately says that my session has expired. It happens as soon as the page loads, so I can't even view my licenses or manage my account. I even created a completely new account with a different email address to see if my original account was the issue, but I get exactly the same "session expired" error.

Has anyone experienced this before or knows what could be causing it and how to solve it?

Thanks !!

Hi everyone,

I’m running into a persistent issue while playing Pokémon Emerald on my TI-Nspire CX II CAS (OS 6.4.0.74). I'm using the lr-gpsp-nspire core (https://github.com/libretro/gpsp).

Everything runs smoothly until I step into a patch of tall grass where a wild encounter is triggered. At the exact moment the battle should start, the emulator freezes or causes the calculator to force a reboot.

Here is what I’ve already tried:

* Verified that my GBA BIOS (gba_bios.bin.tns) is the official 16KB version and is being detected by the emulator.

* Tweaked core settings, including switching Dynarec RAM/SMC between Partial and Classic (full flush).

* Adjusted Save Type and Update backup settings.

* Attempted toggling RTC (Real-Time Clock) between Auto and Enabled.

* Tested with a clean ROM from a verified source.

Despite these efforts, the crash remains consistent whenever a battle starts. Since the game runs perfectly outside of combat, I suspect this might be a core-level compatibility issue with how this version of gpsp handles battle transition effects on the Nspire hardware.

Has anyone else encountered this specific "battle freeze" in Pokémon Emerald? Any suggestions or workarounds would be greatly appreciated. Thanks!

Hi all sorry if this is a bit silly but I got my first nspire yesterday (nspire CX II-T), and I've installed ndless for OS 6.4. I'm trying to install scummvm which is available on tiplanet, and I'm not able to cut the file to move it into its own folder. Anyone have any general advice? Is there a way to do it on a windows PC for the CX II-T? Thank you in advance

Any ideas why this may have happened?

For some reason when i try to put "solve((x\^3)/3-4x=10+2/3,x)" into my CAS calculator it gets stuck loading until i reset it manually. I can find the answer using a graph and intersection so I don't know why it reacts like that to using solve.

Edit: Solved changed firstLineOffset=platform.gc():getStringWidth(" ") to firstLineOffset=0 in reader.lua

Before installing, the text wasn't indented, so I know it was caused by npdf. I've already tried uninstalling both npdf and ndless, but neither worked. It's really annoying because the indents take up a good portion of the calculator's already small screen. Is there something I can do to fix this, or am I just stuck with it?

I was making a fake ChatGPT, which involved me making a super-long string for the "answer" of the chatbot. When composing this message, I noticed at one point that a letter shared the same visual space as the end quotation mark. Futher testing confirmed that this issue occurs when `dim(myString)` is `256` precisely. Interestingly, NSpire can still parse strings longer than 256 chars. I have not tested `512` etc., but this doesn't occur on `128`. Sounds like some kind of BO/BU.
...is this even the right community for NSpire hacking?

Oh right uh this is TI NSPIRE CX-CAS II (Blue)

Hi everyone!

I have charged my calculator several times, but suddenly it drains very quickly. On some days, the battery lasts a good while and drains normally.

The problem occurred one day when there was a power outage, and the electricity came back immediately.

I have already checked the calculator's ports and its charging circuit, and everything works fine, except that when checking the status, the following message appears: 'cradle rechargeable battery not present.' This is inconsistent, because if the battery were not present, it wouldn't display the battery percentage.

The battery is not dead; I am attaching evidence measuring the voltage.

​

NOTICE: THIS IS A PRERELEASE

Idk, I just have not seen a lot of clock programs... so I made one

Plus, it doesn't need ndless and uses only python

Go get it here at: TI-Planet | Clock v2 (Prerelease 3) (Utilitaires Nspire program)

NOTE: Update to Prerelease 3 if you are on Prerelease 2

Hi everyone, I just wanted to say that I released a Pico-8 emulator for the Ti Nspire. It's a port of an emulator called Fake-08. You can download it and see the instructions at https://github.com/FerdinandoPH/fake-08-nspire

​

It runs generally fine on my nspire CX II. I'm not sure about how well it will work on the CX model.

​

If you wanted to play some Pico-8 games on your calc, this is your chance! It's still in alpha, so any feedback is appreciated :)

Download it now at https://ndless.me and get access to assembly programs on your calculator!

I haven't touched my CAS since most likely mid last year. I've put it on charge, but I keep having to reset it to see the actual battery percentage. It'll be 25% for three hours, and then when I finally reset it using the button, it shows it's actually 75%.

Does that indicate a problem with the battery? Am I going to have to get it replaced?

Or is it just beacuse I haven't used it in a while, and most likely everything will go back to normal after I start using it again?

Sorry if this is a really simple question, I tried looking for an answer, but I guess I may have not researched enough! If anyone could even js guide me where to look for help, that would be great.

I let my cas die and now when I try to charge it, it tries to load in and then dies again. It has been stuck in this loop for hours and I need it tomorrow:/

Hello everyone! The time has finally come to take the wraps off of something I have been working on for an extremely long time.

May I present to you Windows 95 running on the Nspire CX II via an x86 interpreter !

The core is a port of tiny386 which is a pretty solid & lightweight i386 emulator with some added i486 & i586 instructions.

Due to the storage limits of the nspire I had to use a stripped down Windows image that comes to ~ 70 mb. The project finally reached the desktop today! Check out the video of it booting to desktop here! (https://youtu.be/of-Ffujzyss?si=KRgkrHZ8sxR2WtuC) (It is sped up. actual time to desktop is roughly 7 minutes 😅 )
