This is just another proof, that PSX-Exploit doesn't work with Slim-PS2s.
This is just a way booting Homebrew through Codebreaker and SMS, not the PSX-Exploit itself!
Get some background-information, how it works and you'll see, that original PSX-Exploit never will work on Slims (and if, it will not work the same way, because the old bug is fixed.). :P
