TNOC can generate 3 different files.
- *.tno/*.tnc without boot2  (_WOB2)
- *.tno/*.tnc without sampes (_WOSA)
- *.tno/*.tnc without boot2 & samples (_WOB2SA)

For example, a file called "tinspire.tno" without samples and boot2 will be saved in "tinspire.tno_wob2sa"
Just remove the extra-extension, here "_wob2sa".
If you don't see this extension, make shure Windows display the known extentions (In explorer, go with [ALT] key to Option > Tools > Display) (even if Windows shouldn't know this extention lol)

I haven't made a parser function that decomposes the entire path to save the file in a new folder or what else, I just made this quick function =)

ok, thanks, though a pruned OS 1.1 does not send right :)

There's nothing to prune on OS 1.1.

Here are the maximal free space sizes, with all pruned and original TI-Nspire OSes:



With OS 1.4 or later, you can increase your free space by 2-3.5Mb by using the TNOC tool.


If new OSes go on being bigger an bigger, users are going to have problems when upgrading/downgrading, because the free space won't be enough to store the temporary tno/tnc file during installation.

They'll have to remove the OS through the maintenance menu before...

TI is so stupid...

Is it possible to also remove the 84+ emulator? I don't use it anymore, so that would save me another couple of megabytes.

Without the RSA private production keys, no.

Not even the 84 flash image? It seems like that would be stored in a separate file.

The 84 rom is stored in "TI-Nspire.img", which is protected by the RSA keys.  If we could edit that, we could easily flash the CAS OS image to the non-CAS.

??? The 84 flash image is of course modified by the user, so why would it be inside the os image? (it would mess up the checksum after being modified) Or are there two images - the default image and one stored separately that the emulator can modify?

I believe this is the case.

Then, it would be easy to write an ndless program to delete that file. I would do that if I knew where the image was stored.

Not necessarily, but if you want to try, it is in the directory /ti84/ of TI-Nspire.img.  There are several files you would need to delete, though.
