Rooted Nspire document browser
« on: April 21, 2011, 02:47:34 pm »
By changing some strings in the OS image, you can make the document browser view all files in all folders.
I can't publish it here because I have changed the values in the phoenix.raw file.

I want to make a patcher for this, but the "documents" string is located at 0x6807F8 in the raw image.. just fill it with 0x00s

It is for CAS 2.0.1, I don't know if it's the same in non-CAS.

EDIT: This will not show any files, I had to fill all ".tns" strings with zeros too, currently I'm looking which of the replaced ".tns"es is responsible for file displaying ::)

I think the address for the OS 3.0.1 (1753) would be 0x864AE8 (phoenix.raw, CAS model) and fill with 0x00s until the end of the string.

NOT TESTED...

I'm really not trying to derail your thread, but does anyone have suggestions on getting OSLauncher to load DummyOS? Every time I try it, I get short lines on the display and the nspire locks up. (nspire non-cas, OS 2.0.1)

Also, do you know the size of the decompressed OS image for OS 2.0.1 CAS or basic?

It would be best if this was shown to work on a real calculator :)
Indeed, that's where the main problem lies: modifying an OS image, and launching the modified version, in such a way that it will work on a real calculator - and preferably work reliably - is much harder :)

Note that OSLauncher takes zipped files as input :)

Of course ;)
The note was more aimed at mikehill than at you, because he was asking for the uncompressed size of phoenix.raw.
