First off you Need a Tool/Debug PS3 to do this.
Getting a Debug Package
Your asking “How do I find a debug package?”. For starters, check PS3-Debug.PS3News.com for a debug patch. But, if its not at the site, its somewhat simple to check for it.
Boot up your PS3 to the XMB, make sure in debug settings that NP environment is set to “sp-int” or “prod-qa”, sign into PSN (with sp-int or prod-qa credentials, you can use the quick sign-up), and launch the game. If your in luck, it will say an update is available – download it!
To get the URL you have a few options. You could either sniff out the connection with something like Wireshark - that takes a bit more setup. Other times the URL is actually passed right to dtccons - so make sure you have the debugging windows open. Or, you could use any number of the PS3 Proxy applications to grab the link.
