PRX Loader on XMB...

peb · Post by **peb** » Sat Feb 02, 2008 11:38 am

Hi!

Well, my final goal is to be able to load an EBOOT.PBP at the start of the PSP. I tried several methods (i’ve tried to use « autorun » in the « recovery »,to load a prx before the loading of the XMB…) but no one of this methods works, and I think it’s normal because the modules prx of the psp are not yet load in each one of this case.

So I’ve used another method, which is to create an active prx on the XMB but which load the EBOOT.PBP only when I push SELECT.
But the prx is unable to load the EBOOT and I dunno where I can made a mistake.

Here is my source code :
