Can you play 2 same games on a PS2?

[Eric]

here is the thing i have 2 copies of gta vice city, one is greatest hits and other is a first edition, i wont restart the game and play a new copie but the PS2 wont load it ,so do i have to delete the gta vice city memory card

[Rabbit]

Yes

[mmmssmm]

The data for the 2 games is different so I guess it needs 2 separate space for save files.

It doesn't requires you to delete anything.

But if the game wont load/work then it could be the disc is screwed up.
