Follow the tutorial it's very easy damn it :p :
-put .rap file inside "exdata" folder in the USB and Activation.pkg on the root of the USB.
-Plug the USB on the right slot (the one near the bluray player)
-Install the activation.pkg and create a new profile and name it aa then
run reactPSN v2.23 and the ps3 should restart itself with the newly
created profile being renamed to "ReactPSN xrif xedat".
-You are done now you can log in your original profile and play PES 2013 online for free
