Early beta of nspire version string patcher
« on: August 07, 2012, 08:14:31 am »
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 XD
By the way, it has been a long time since the last time I saw you. Are you still working on nspiremovieplayer ? :)

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

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

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That would be even cooler as you could trick the software that you have a newer version of the OS installed.

I've got better and shorter :
Code: [Select]
#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.

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

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.
