Early beta of nspire version string patcher

[tangrs]

For a bit of fun, I made a version string patcher for the Nspire.



It's still a WIP requiring polish but it works for now

I'll publish binaries soon but the impatient can see how it works by visiting the github repo https://github.com/tangrs/nspire-version-patcher

Lol, that is awesome
By the way, it has been a long time since the last time I saw you. Are you still working on nspiremovieplayer ?

Most of the development in nspiremovieplayer is finding a faster way to decode JPEGS. So there is research work going on behind the scenes

Glad to see you're still having fun with the Nspire
Also, nice application. I wonder, can you spoof the version number that the Student software detects ?
That would be even cooler as you could trick the software that you have a newer version of the OS installed.

how is it possible to find the location of those things? the more apps like these i see, the more confused i get xp

nice work btw, really nice and i like it how you call it android xp

I've got better and shorter :

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

#include <os.h> #include "libndls.h" static unsigned addr_addrs[] = {0x107C1DDC, 0x10801E3C, 0x107A2DC8, 0x107FF0D0}; #define addr ((unsigned *)nl_osvalue((unsigned*)addr_addrs, 4)) int main(int argc, char* argv[]) { char lol[]  = "Whatever you want"; char * lol2 = malloc(sizeof(lol)); strcpy(lol2, lol);     *(addr) = lol2;     return 0; }

el problemo ?


Edit : oh, and by the way, show_msg_usr_input() does not work in the current revision of Ndless because my patch for it didn't yet get pushed to the Ndless svn by ExtendeD.

@levak
how come your ':' are messed up a bit? since they have a space in front of them, and the third one even totally dissapeared

[adriweb]

Very nice both of you ;-)

Wow nice, so basically we can change most of the system menu text and stuff?

[Wayne]

Yeah TI finally released 4.1.1

You thought is was not possible ?
It is just a matter of time, a matter of goal and a matter of usability.

With Ndless, you can run any ASM or C code, so you can basically modify any value, any code in the OS that is running.

Awesome levak

so now we can trick the sending software by telling it we are running another OS?

Seems so, indeed
