 Posted: Sat Feb 13, 2010 6:59 am Post subject: Spoofing module version |
 |
|
This would normally be a fairly easy thing to do (I already did it), however, I know vshbridge has its own loadmodule, and I'm presuming its own querymoduleinfo.
Does anyone have any information about those vshbridge functions?
If not, does anyone know how I can edit an already-loaded modules version? I know psplink loads up a list of modules (And I think their versions), and since those hardcoded versions are well, hardcoded, how would I go about editing it? I think it's exported, I just don't know how to look up variable exports, as opposed to function exports, if there's any difference (I couldn't look up either in syslib for the sceVshNpSignin_Module)

There you go. Have fun.
| Code: | //change module version
unsigned int alterModuleVersion(const char * name, unsigned char major, unsigned char minor)
{
//result
unsigned int result = 0;
//find module
SceModule * mod = sceKernelFindModuleByName(name);
//tada - it's loaded
if(mod)
{
//change module version
mod->version[1] = major;
mod->version[0] = minor;
//we are done
result = 1;
}
//return result
return result;
} |
Requires you to have loaded the module already, so it gets linked into the module list.
If it ain't loaded, this function will do nothing and return zero, if it is loaded it will change the displayed version of the module in the module list.
I don't know whether this is what you wanted, if not feel free to ask for more help and I shall provide.

I think that's what I needed.
I thought it was readonly so to speak (Copy the structure over), and it couldn't be edited that way. I think I was wrong.

Not trying to be nosy but... for what do you need that?
Did you discover some check that requires a specific module version or something of the sort?

No, I thought it did for a while, but then it became curiousity.
It noticed an 0x05000010 on 5.00 M33-6 and 0x05050010 on 5.50 GEN on npsignin_plugin.prx (I had dumped it and such before it was decrypted). I thought it was kinda odd. Also, it's exported.

Well I noticed that the Adhoc Library (Net Libraries in general...) have been changed on the jump from 5.00 to 5.50...
They remained the same from 5.50 till 6.20 though... ;)
Version 1.3 is on use on 5.00 while Version 1.4 is the latest one at the time of writing this article and is used up to 6.20...
I'm still trying to figure out some of the changes myself... as I'm really interested in the networking aspect of PSP.
