Sorry about that. You should buy an Xbox on ebay. I had 2K5 for PS2 but purchased an Xbox, Action Replay, a laptop PC and 2K5 just so I could use Finn's editor. I could never ever go back to the PS2 version.
Here's how you can get the rookies and other players that want to create. Download Finn's editor and then download my roster file. Open the file in Finn's editor and then just copy over the information for your PS2 roster.
