Proper save size for Pokemon games

Can anyone tell me? I used to use a DSTT, and it gave me a 1MB save size for Pokemon Platinum. When I switched to my Acekard 2i, it gives me a 512kB save size. What's the proper size?And, while we're on the subject, what are the proper save sizes for the rest of the pokemon games? Diamond/Pearl and Heart Gold/Soul Silver?

Well its probably depends on the card, different cards use different save sizes, I use a R4 and AceKard2i and they are both 512 kb

well most cart use 512 format, so go with the majority, I think..lol

i always used default and it worked fine with me

Well, Zelda Spirit Tracks for example needs a 1MB save, and people were saying Platinum did too...

then the default file it is...
