PS2 Memory card question

[Concept]

I'm about to fully start Katamari Damacy on my US PS2, but when I ordered it I forgot to purchase a memory card as well. All the ones I've bought so far have been European. So before I start the game and loose all my PAL data, will saving a US game on any of my current memory cards wipe over the already existing data? Or can both formats happily co-exist on the same card?

Cheers in advance.

My card has saves from the US, Jpn & The UK all happily sitting next to each other

Excellent. Thanks for the information.

Katamari Damacy from my brief play of it so far has been gob-smackingly wonderful.
