About the freeze at boot time for OS 3.1:
Ndless installs itself in the OS image of the calculator with hard-coded addresses. This OS image will also be read by the hot-run OS at boot time: this will trigger the Ndless hooks, but with a version mismatch.
But it appears it isn't the only issue which avoids booting OS 3.1.

Bump:

I was wondering if you had any luck with CX compatibility yet?

Also in response to Hayleia I don't think it matters anymore if it's a good idea to release this or not. The harm was already done with PTT patches and fake mem clears on the TI-83+ years ago and since then, TI has taken a strong stance against third-party hacking and when TI-Planet people tried to convince TI that Ndless was not meant to cheat, it was already too late.

I would say that at this point, what matters the most is that no cheating tool comes out on the Casio PRIZM, since Casio has given us a chance that, IMHO, we should not blow up. With TI it doesn't matter, since they screwed with us too much already.

Yeah, they might never change their mind . I was just pointing out the fact that it is sure that they will not change their mind if OS Launcher keeps being updated, not saying that discontinuing it would change their mind in one day.

I agree. Even if it is less powerful, it will always be able to run  programs, without waiting for months before the jailbreak. I need to buy one by the way

Yeah, in fact if OSLauncher and other tools that can make cheating much easier would start causing too much damage such as TI-Nspires all getting banned from classes then hurt TI sales enough, this could even go as far as TI dropping out of the calc market (although they could just make a new CAS-based calculator that is totally different from the TI-Nspire, hardware-wise). Of course, however, OSLauncher is not very popular and can be hard to use, so that makes it less likely to allow way too many people to cheat.

[Lionel Debroux]

Everybody (people from the community and TI) ought to stop fearing OSLauncher: it's harmless

And the Nspire cannot be banned from exams, let alone classrooms.
Indeed, even if the Nspire's PTT mode proved to be as shitty as the 84+'s PTT mode is, all it would mean is that the Nspire is equivalent to a calculator without a lockdown mode as sophisticated as the Nspire's PTT mode is supposed to be; but calculators without a sophisticated PTT mode are allowed in the main standardized tests. Even if we all know that the people regulating standardized exams are flat out incompetent (because they feared OSLauncher, while the PTT mode precisely makes it possible to disable it), they can't ban the Nspire without banning all other calculators.

As for classrooms... well, hundreds of millions of dollars (if not several billions) were spent by the school systems on the Nspire technology, and TI's T3 program has trained dozens of thousands of teachers on Nspire technology. The Nspire is supposed to counter cheating better than other calculators do... so if that very platform were to be banned, what on earth would the school system choose ??

So nah, don't lose sleep over OSLauncher

Here is an updated version that supports file extensions. It will still use /documents/ndless/phoenix.raw.zip.tns if it is launched directly.
And it has a theoretical CX support, but launching official OSes still fails.

SilverOne on TI-Planet has discovered that launching any OSes < 3.1.0 will work when OSLauncher is in the ndless/startup folder, so launching CAS OSes on non-CAS devices should be reliable now (link, but the menus will be messed up). Sadly, this method doesn't work on CX calcs (tested in emulator).

[kevkid]

Just an idea, but since the menus are messed up, why not when hot booting the os, make it load the menu icons from say a folder in the user storage rather then from the actual rom installed on the calc. For example if the os 3.02 is hot booted when throwing it on the ram, make it load icons from a folder rather than from the installed rom. Or maybe when the program is executed, make it load the icons (which are stored in the user space) to the ram then the hot booted os will load those icon from the ram rather than from the installed os. Dont bash me too hard lol.

It requires patching the OS, which in turn would require more reverse-engineering effort than we spend on it

[sammyMaX]

Was the icon problem present before?

Edit: compu, I think you meany /documents/ndless/phoenix.raw.zip.tns, right?
Edit 2: It works! And the logo problem isn't that bad (I thought you meant the catalog and the math functions were going to be screwed up too!)

[Lionel Debroux]

Yup, it has always been present.

Well, it was Excales idea  so i can't take all the credit ^^.

What do you mean by file extensions support ?

[zAnt]

With school coming up, it'd be pretty amazing if this could have some CX support

Or is it possible to even emulate the Ti-89 on the nspire?

[TheNlightenedOne]

It's possible, and calc84maniac (I think) was working on one, but then his hard drive failed, and he lost his code and stuff.

Anyway, it would be quite slow, and you'll need to remap the keys.
