They're official, so they're garanteed to work. Unfortuneately, none of the codes you specified are on that site, but I'll do some more snooping. Hope that helps!
You need a cheat device, like Action Replay or Codebreaker. With that, you can type in cheats. This thread mainly deals in Action Replay, so I'd get that if I were you.
Yeah, none of the good codes work for me, especially joker codes. Even when I use them in the Hall of the Cornerstone.
I think I'll try Codebreaker next time, if I get one. That way there'd be more chance of the codes working, seeing as I have another cheat system to fall back onto. :¬)
Actually, I think I might re-enter them. Maybe I typed them out wrong, but the AR Max just didn't pick it up. It may not have been an invalid code I used, just one which didn't work.
Anyway, on the subject of codes, I've decided to test some of Datel's codes, as some people have said they don't work. And, I have to say, it's the same for me. I tried all the stat codes, like the max strength, magic, defense etc. Still no worky, for Roxas, Mickey or Sora. I wonder if I could try porting some of the NTSC ones. Do you think that would work?
Yeah, I just want that whole... feel to it. Make it feel like Critical Mode.
I wish I had WinRAR and Deltamaker. So I could port it myself without having to ask people to do it for me.
UPDATE: I now have WinRAR and Deltamaker. That took what, two minutes? Now where do I start?
Wish I did, KHRiku. I don't have any of the moveset codes, except this strange one which makes the keyblade fly around everywhere. Like in the Roxas battle.
It wouldn't, no. I'm trying to get somebody to port them.
