I've had a development. It can be done. A PS3 roster update. It can be done easily with the right equipment. The big problem is I don't have the necessary equipment to do it on my own. Here's how it's done.
The main objective is to create a .psv file with the roster on it. If Samoan Stallion can give us his working PS2 roster file on a memory card, this needs to be converted to a .psv file.
I have a ps2-ps3 memory card adaptor. If he sends me his memory card with the updated roster on it, I'll transfer it to my PS3 and send the memory card back with a tenner for his trouble. Or alternately I could send him my memory card and then a tenner after I get it back.
Then I can pull off the new .psv file from my PS3 and put it up for download on TRF.
I can't get the PS2 roster file onto my PS2 memory card, as at present I don't own an Action Replay Max system. That's the only thing I need to do it myself and seeing as it's only for one game and I'm selling my PS2 soon, there's no point me buying it.
So, Samoan Stallion I guess I better PM ya. EDIT: Just noticed, he's a UK man, that'll take too long.
K-Pac do you have access to Action Replay or Slide Magic tools at all?
