Ndless VS arTIfiCE

I updated my calculator before I learned about Ndless and, from what I've read, there's no way to do a rollback. What are my options? Is there some program that can rewrite the OS or something? Is there a workaround?

The CEs are a good for numerical calculations and have a pretty active developer base which makes them great models to learn to program with, if you intend to use or want good programming functionality, these are the best models for it imho. The Nspires, especially models with CAS and that support Ndless, are good too (I've barely used mine ngl so idk what to put here).

That said, the hardware in modern calculators, especially CAS related ones, is quite powerful. Various hobbyists have actually developed tools to deploy relatively heavy Linux distros onto TI Nspire calculators. Practically speaking, they're pretty unwieldy and slow, but it is possible.

ndless

if you're talking about the TI-Nspire series, then yes through the toolchain/SDK of Ndless, the unofficial/fought-by-TI "jailbreak" (see here). It's a typical arm toolchain, so C/C++/ASM is supported (and more with enough work), and lots of things have been created and ported along the years.

As another person already said, there no builtin way to do that since you have the non-CAS version. However you can use third party CAS engines, like KhiCAS, if you're able to install Ndless (if you don't have a recent OS version it should be doable - check https://ndless.me)

I’m planning on installing Ndless (http://ndless.me) onto my CAS to play Minecraft (yes, I know… it’s dumb) and do fun little projects like programming a game on the CAS.

Emulator most likely require ndless to be installed (nspire jailbreak), sadly it’s version dependent, which is why I don’t advice anyone to upgrade to the newest os. Which that said you could explore the ndless apps (which has seemingly just shut down) which offer a mini Pokémon for example - this is not (at least to my knowledge) the „OG game“, but people definitely tried there best to make it good

I can recommend ndless to you, since it opens quite a lot of possibilities, like cas calculations via KHICAS, emulation support and neat other stuff that could be potentially useful (like a fake light), remember to NOT upgrade to the newest os, but to one on the list shown on the ndless website, which can also be found here.

-> get ndless from ndless.me -> go to ndless-apps.org -> look for PokeMini and install

Sure. Just make sure to get Cesium (and AsmHook if you want) via arTIfiCE, so you can launch ASM programs/games easily.

Sure but on 5.5 and later you'll have to go through arTIfiCE first and install Cesium/AsmHook before you can launch ASM programs.

If your calculator runs OS 5.00 or higher, you cannot download games. However, you can work around this by jailbreaking it, but be warned: there is a possibility to brick your calculator. For more information on how to do this, download arTIfiCE.

(If using the CE, you may need to use the Artifice Jailbreak to run programs, you can also use it to install shells like Cesium.)

Just use arTIfiCE, then Cesium and/or AsmHook to be able to launch asm programs just like before. Those 2 programs are linked from that page.

Yes follow the steps here: https://yvantt.github.io/arTIfiCE/

click 2nd, +, 1. if your version is 5.5 or newer, follow the instructions to run ASM programs on your calculator via arTIfiCE (side note: ASMHOOK is vastly easier to use than Cesium, I highly recommend using the former). if your version is older than 5.5, skip to step 2.
