Kingdom Hearts 2 Final Mix Codes Situation

Okay so I have been searching for working ways to put codes onto my final mix for about 20 hours no. TO NO AVAIL.

Here has been my process all day:

75% googling my ass off.

looked for way to input codes via my play method (Swap Magic v3.8 Coder)

found codes, couldn't find an immediate master code for raw/codebreaker (raw codes work in swap magic 3.8 right?)

found max codelist manager for easy code input via burnt cd with desired codes. (ARMAX converted codes using omniconvert)

NO codes worked period. tried all sorts, basic health mp drive etc., party member replacement nothing

figured, hey i keep hearing these codes will only work with codebreaker

*googles ass off*

finds very long and complicated way to get cracked codebreaker to work via swapmagic

realizes i have no jump drives on hand

eventually finds a mastercode for raw/codebreaker (turns out converted armax code was the same all along)

inputs raw codes on swapmagic, nothing.

after countless hours of burning googling and straight getting pissed off as anything i end up posting here.

Can someone PLEASE walk me through what I am missing? Am I not using the codes correctly? I'm almost 100% sure I'm inputting them and executing them correctly. I am seriously tired of searching and have decided to ask for help. *heart drops*

So once again, my play method is: Slim ps2 (2008 era maybe? don't feel like getting up to check this very moment but will if asked), Swap Magic 3.8, Kingdom Hearts 2 Final Mix backup.

Appreciate any help as I am at a complete loss right now.

 

It should work through Swap Magic, maybe you used the wrong codes? Or forgot to enable them in the menu?

 

I cant help you with swapmagic, but if you softmod your ps2 (Sooo much easier + it works on pretty much every ps2) then I'd be happy to walk you through everything.
