help! we love katamari won't save

we love katamari refuses to save on my 64mb MaxMemory memcard.
it always said something like "there's not enough space" although there's just a few savegames on the card.
i copied a savegame on my card manually using execftp and now i can load it in the game but i'm still not able to save ("save failed")!:banghead:
is there any way to fix this problem? maybe using AR-codes or something?
it's the first game i've had saving-problems with and i don't want to buy an original sony memcard just for one game...

thx

Some games just aren't compatible with the maxmemory cards. I have had trouble like this before, some won't even boot. For such problematic games you need an original mem card.

bad news... -____-
what other games are incompatible to maxmemory cards?
if it's some interesting ones i might consider buing a sony mc.

Sorry...kinda forgot about this thread. The only game I can think of is Delta Force: Black Hawk Down. This game will not start with my 32 meg card in.
