Need help in Hacking FF-X Code!!

[chien_me]

Yo guys....I'm working on these codes I got from CMGSCCC :
2AACC91F 240200FF
2AA8C91F 03E00008
2A94C91F A0620268
2AF739D7 08030088
These codes enable EVERYONE pull off unlimited overdrive In Battle (Final Fantasy X)
Now,I know that if I can alter these codes somehow,maybe I could get what I need :
Unlimited Overdrive In Battle for ONE particular character,say...for example Character in Position 1,which probably be Tidus.
Now,if you guys can help with my problem here,I would be very grateful.I already tried removing the second,third,and fourth code,but it doesn't seem to work.FYI,I have no experience in hacking so I can only guess.So,if you guys can come up with the code,please post it in your reply,ok?

you can joker the code sp all you have to do it hold the top buttons to fill up your overdrive guage

Sir Lionheart,I'm very grateful for your help,but the code you posted is not the right code that I'm asking.You see,the code you posted is the overdrive code for BEFORE and AFTER battle.I already tried the code,for example let's just say Tidus.When he entered battle,yesssss...the overdrive gauge is full alright.
But,when you use it once.........it's back to nil.empty.
Now,what I want is....In Battle....you can always have an UNLIMITED overdrive gauge.I already got the code for EVERYONE to pull off their overdrive unlimited in battle.
2AACC91F 240200FF
2AA8C91F 03E00008
2A94C91F A0620268
2AF739D7 08030088
(it's in codebreaker format)
I'm working on how to alter these codes somehow so that the codes above no longer affect ALL Character in battle,but only ONE particular position.for ex-Position 1,or Position 2,it doesn't matter which position it is as long as I can put Tidus,my favourite character in that spot.
So,anyway......thanks a lot for your help.hey, if you come across the code I'm asking or maybe you know a friend of yours who can help me with this problem,I would be really really grateful.Once again Sir Lionheart,I thank u.

To GMO...hey...that's a good idea.Actually..I've been thinking about that too.But....I don't know the joker code of Final Fantasy X.Please GMO...if you know it...can you post it in your reply ?
oh...btw,will the joker code work on codes that have more than one line ? As far as I'm aware of...the joker code will usually work fine on one line code.More than one line...well...it sometimes work and sometimes not.Sorry for the trouble...and thanks for posting your reply.
