Win98 or 2000

[POSTRIGHT]

hi m8
its nothing to do with the memory (no offence reply 1)
you will find that metal gear solid 2 is over 4gb in size!!
Win 98 uses fat 32 to format your hard drive(s) and will not hold any file over 4gb. So unless you spilt it up
you will never copy it

UNLESS - - you change to win 2000, and use NTFS to format your hard drive(s) (and NOT FAT32).
NTFS allows files of over 4gb and will easy save a full dvd of 4.7gb and more.
then you can easily do your own PS2 backups

hope this helps
Enjoy
