Hi,

As you may know, since OS 1.2, TI does encrypts TNS files. Since then, two methods have been developed to retrieve the XML data:
-Using a script with nspire-emu: http://ourl.ca/12404/246559
-Using copy/pasta on TI-Nspire Computer Software: the Levak's Clipboard Dumper

These two methods both have pros and cons (as well as what I made  ).
So, TNS2XML uses yet another way: it retrieves the XML data when you open a TNS files, directly on-calc, which can be very useful for some developers.

You can download it here: http://tiplanet.org/forum/viewtopic.php?t=9295

If you have any question about it, don't hesitate to ask .

Very nice work Excale

Well, it would be possible to make a full editor on-calc, but I can't see any practical use for it... The only self-made TNS I've seen so far are Notes (Nspire Text Editor or nCreator) or 'trolling-documents'.
(Also, saving the docs on-calc means fooling the Nspire with XML data it never asked for, which is much harder to do than just reading chunks of decrypted XML ).

Well it's based on a hook, and there isn't any call in ndless to uninstall them.
Hopefully Extended will make this sometime

Well, a hook places some jump instruction somewhere in the memory, jump which leads to some code. In my case, I placed some hook at some addresses in the OS which get executed when the Nspire retrieves the XML data.
The good thing is that I did not have to search how the XML is decrypted, but the bad thing is that since I have no idea how to decrypt it, there is no way I can make the same on PC (except in nspireEmu).
