I always thought that you can save Uk and Us savegames to the same memorycard, but you would need own card for japanese games. Dunno, i might be wrong about that.

"Also, you'll need to use separate memory cards for Japanese and UK/US game data"
"It's not possible to save both Japanese and UK/US game data on one memory card; if you try to use your existing memory card with Japanese games it will automatically be reformatted. Likewise, if you try to save UK/US game data onto a memory card which contains Japanese game data, the card will be reformatted"
"My memory card data was corrupted though when I mixed US and UK formats so I would not recommend others make the same mistake"
I'm getting mixed messages about this. Damn.
Nothing's cheaper than something free.
F1 vs FOTA, when too much power is in couple peoples hands.
