cooleyes · Post by **cooleyes** » Mon Oct 08, 2007 7:05 pm

use the code in psplink, I can hook a func in prx loaded(PSP_MEMORY_PARTITION_KERNEL)

but it can not hook a func in prx(PSP_MEMORY_PARTITION_USER).

anyone know how to do it ?

no one know this? :(

I can get the func exported address like 0x9xxxxxx, is not kernel memory address,
so I can not find out the syscall_addr.

You can probably hook the import (instead of the export in psplink), so find the module which is calling the exported function and do a 'apihook @importmod ImportLIb @function/nid

Maybe psplink hook's could help you.

I tried to use it, the code is working and I think he could help you, but me I have little problem :

I call psplink hook's and I run the EBOOT2 which not start ... when I quit EBOOT1, the EBOOT2 start! It's normal when you read the code, but It's not same result like psplink ;)

I think you can use this code but change only LoadExec by LoadModule.

EDIT: sorry, I didn't see you use this actualy XD
