Ok, all resolved!
I'm not using esported functions!
Now I've built a prx that load the executables in a determinate mode, all passed with arg!
Thanks very much for all!
Oh, excuse for my very bad english, but while writing my problem I learn english! ;) |

Pirata Nervo, (maybe) I've a solution for you!
I've passed 4 args to prx and for that I've used only a string!
Use strtok to divide the string!
This is a example:
| Code: |
char* arguments = (char*)malloc( strlen(path) + strlen(target) +1);
sprintf("%s{%s", path, target);
sceKernelStartModule(mod, strlen(arguments), arguments, NULL, NULL);
|
And in the prx use strtok to divide the string on '{';
The only problem that I've encoured is that you cannot (I think) pass a very long string, but is only a possible problem of one of my function not a limitation of LoadModule funct! |

lol I knew How to pass the arguments but it's easier for me to add just a new line to my writeFile function instead of adding a new value to a for loop, creating a new string, etc :P
Thanks anyway.
About the size of the string, you can have a very long string as long as you allocate it :)

you can't load kernel mode pbp's unless you have 1.50 kernel addon installed on your psp.
THat's why we use exports :P

no.
exports are made to don't use kernel mode pbp's and use kernel mode functions exported from kernel prx

shouldn't it be "nope" ? because we don't speech "nop" and "nope" the same way : "nop" probably as in "top", "nope" probably as in "slope" |

I tried the follow code , it's ok.
| Code: | int main_thread(SceSize args, void *argp)
{
sceKernelDelayThread(10*100000);
// Hook exit game function
SceModule *mod;
mod = sceKernelFindModuleByName("sceLoadExec");
if(mod) apiHookByName(mod->modid, "LoadExecForUser","sceKernelExitGame", exit_to_mypspmenu);
sceKernelExitDeleteThread(0);
return 0;
} |
but when I change the code to :
| Code: | int main_thread(SceSize args, void *argp)
{
// Hook exit game function
sceKernelDelayThread(10*100000);
SceModule *mod;
mod = sceKernelFindModuleByName("sceController_Service");
if(mod){
apiHookByName(mod->modid, "sceCtrl","sceCtrlReadBufferPositive", sceCtrlReadBufferPositiveFake);
}
sceKernelExitDeleteThread(0);
return 0;
}
int sceCtrlReadBufferPositiveFake(SceCtrlData *pad_data, int count)
{
return 0; // return 0, do nothing when key pressed.
}
|
it won't work.
I want to hook the controller function. but It seems not work. i don't know why. |

Try to use this funct:
( Are you sure about sceController_Service? Where I can fine the name of all the modules? )
| Code: |
u32 orig_funcs;
int FunctPatched(void)
{
return 0;
}
orig_funcs = sctrlHENFindFunction("sceController_Service", "sceCtrl", 0x1F803938);
sctrlHENPatchSyscall(orig_funcs, FunctPatched);

yes sceController_Service exists.
you can check the libraries names here http://silverspring.lan.st
NID: 0x1F803938
@ldqmoon, your "fake" function only returns 0. it does nothing.

@ldqmoon
Use the functions from the M33 SDK.
| Code: | int sceCtrlReadBufferPositivePatched(SceCtrlData* pad, int count)
{
//code
}
u32 OriginalFunction;
OriginalFunction = FindProc("sceController_Service", "sceCtrl_driver", 0x1F803938);
sctrlHENPatchSyscall(OriginalFunction, sceCtrlReadBufferPositivePatched); |

Yes, I've know a way to get the NID of a funct.
Thanks Pirata Nervo!
Super Sheep, your funct is the same as my... |

| No it's not. My function can actually do something. Yours will constantly return 0. So the PSP will detect no buttons pressed. However i guess you're right since thats what he wants to do for some reason =/ |

| Oh, yes, my PatchedFunct is only a sample, the function has to be changed as yours, but you have specified the correctly arg! |
