How much memory do i need to leave on tt memory card?

Someone has said my 4gb memory card can only hold 1gb of files and the rest is needed to save the games, is this correct?Regards

Yes you will need to have space for the sav files but each file is only 512kb which is very small basically two save game adding together will only one 1mb so that is not worth worrying over what you need to take note of is leave some slack on the memory stick around 500mb so everything wont be congested ^_^

save games typically take up 512KB per game, so no.

Thanks guys i can now go and be a smart arse!!!Suz
