I don't really know, but I remember reading about Boot issues with OS 2.1. Boot2 1.1 can't run the non-CAS 2.1 OS (it's too big). There aren't any problem with boot2 1.4.

Please look at my edit. I hadn't realized all of what it could do so I thought it was not as good as it is. It actually is pretty good and apears to be very useful.
Oh, yes  Ok.

I heard that it had the same syntax as Lua. Is that true?
I mean nothing revolutionary is being done. It doesn't seem to be all that different froma regular program
If you still don't understand, just try to create such regular programs on the TI-Nspire and come back after that. Did you even know that the TI-Nspire public programming language was very limited... even the TI-80/81 and Casio programming languages are more advanced! I didn't state it was revolutionnary. This is just information: the "public" programming language, which is so wonderfull according to T3 teachers is not even used by TI to release Nspire documents. They're using a "private" programming language.

Well, the most important information is not that a periodic table has been released... That's not revolutionary. The most important information is that the ti-Nspire now supports a new "private" programming language. And that even TI is releasing documents using this "private" language, and not the "public" one!  And by digging into the code, it seems very advanced for a script: an object oriented script! It seems to handle classes and inheritances! (yes, like C++ or Java...)

Petition maybe?
A hack will proably be our best idea for now.
so what exactly is the scripting language(Lua) doing in the periodic table file?
Lots of things that are totally impossible with the public TI-Nspire programming language. If you don't understand, just try to program something like that on a TI-Nspire without using Ndless.

I wonder if they'll try to sell the SDK and if so when and for how much. I will not pay much for it(most $20) otherwise I can get a copy of it off the internet easily enough if they release it.
yeah that was what I meant. we'lll have to hack it or maybe John Powers will be nice and give it to us
John Powers was allready in the TI-68k development team. I don't think you'll get anything from him by simply "asking" for it.

Are we currently able to use this or will it require a software hack? Use what, the periodic table? If it's a page that can be added to documents, or a program like the scratchpad, I doubt we can use it on the non-CX nspires. If it's a tns, it should work on any OS3 nspire.
I suppose he was meaning "using the script language behind the periodic table". And the answer is no. We can only use it if we get the special software to insert/edit "TI.ScriptApp" widgets. The, TI-Nspire Developer Edition? It seems John Powers has it. No wonder they're trying to kill Ndless. They'll be able to sell that software, and/or the generated documents!

Yes, but they don't have to patch it if they don't want to. Critor has complained to TI about OS bugs, and they haven't fixed them. (If I remember correctly)
If said OS bugs were not part of the math functionality, they'd have less incentive to fix them. I'm sure they'll fix fundamental glitches in the math functions (and didn't someone in that google groups topic say something about a reply from TI that they planned to fix the bug?)
For information, I've reported a math bug giving a bad result with complex numbers on all TI-83/83+/84+ OSes. 2 years ago... They replied with a "thank you", and "we're forwarding to the development team". They never fixed anything... The bug is still there in the 84+ 2.56MP OS. angle(N) with N being a negative real number returns Pi in both radian and degree angular modes. In degree mode, it should return 180. Of course, a human will automatically replace Pi by 180. But a program will just continue to perform its operations using the wrong value, if its developer wasn't aware of the bug.

TI's anti-downgrade protection was broken in 6 hours, compared to 2 weeks with OS 2.1.
* TI Community wins
I'm really happy, this is a great achievement!
This works both for the CX and non-CX, right?
We don't know. We need a CX to check if the modified TCC/TCO file is accepted.

You cannot downgrade the boot2 by using a TNC/TNO file, as the OS will only rewrite the boot2 area if the included boot2.img file has a higher version number.
Is it possible to change the version number, or do we need the RSA keys in order to do that?
We need the RSA keys. It would have been too easy...

i have a question about de .TNC format of the OS files, it can be opened and extracted by 7-zip, it means like a compresed file, 7-zip recognize this files like one of its suported formats of compresion, i mean, ¿which is the compresión format of the .TNC files? i tested TNOC and this program can operate into this compresión format deleting archives, i think that if a .TNC file is modified replacing its boot2.img file with the boot2.img file of an older versión and be instaled in the handheld, it will modify the boot2 sector of the handheld to this older versión, if somebody knows the compresión format please answer my question, is a theory but i would like to try it.
goodbye and thank you for help
We've allready tried last year. You cannot downgrade the boot2 by using a TNC/TNO file, as the OS will only rewrite the boot2 area if the included boot2.img file has a higher version number.

I don't remember who/where, but someone had asked for information about the RS232 adapter. The simplest way is to get an USB/TTL converter. Usually, they are using an FTDI chip.  Then, just connect Tx, Rx, and GND pins to the matching pins on the TI-Nspire. (note: Tx has to be connected to Rx, and Rx has to be connected to Tx) If you have the right kind of electric cable, you don't have to solder anything on the Nspire, and won't loose your warranty.  Have fun.

Since I don't have a Clickpad, I've hacked around a bit in assembly to make this great program work with the Touchpad - it's a really really ugly hack, and the ROM selection screen is still broken (always selects the first ROM in the list), but hey, it's better than nothing! Why is the ROM selection screen broken on the gbc4nspire TouchPad hack?

By the way, what's ticalc.org doing?
The whole english community has to inform about the downgrade protection, before it's too late...
Have you tried sending an email to them?
No. Anybody wants to do it?
