you can use both of them, but i think you wont be able to cheat with swapmagic (unless it's coder version like i have). I have euro ps2 newest model and working perfektly (not to mention that some loadings last much longer than they should, maybe because of my disc, dunno.)
I think you must only have cleared all the worlds, and remember that 100 acre wood is one world as well. I still haven't beaten data-axel, xemnas, luxord, roxas (did beat him once or twice but got crashed before save) or xaldin. I have access to terra. btw do we have gummi codes already? EDIT: and i forgot to mention, im on proud mode and dont have 100% journal (missing chests, crowns and re-minigames)
