Does anyone know how to keep ONE game data and delete the rest of the saved game data for Onimusha?

When I browse the Memory Card, there is only ONE file, but when I went into the game, there are 8 saved game data.

I just finished the game, and I would like to just keep the last one and delete the other 7. Is it possible?

I know I can load the game and save it on another clean memory card on slot 2, but I don't want to fight the last boss again.

Any tips will be appreciated.

I don't know about Onimusha but most games allow you to delete individual saves within the game. Not the PS2 browser . Usually by moving a cursor to "delete" and pressing X. However this is not going to free up any more space on the memory card. When a save file is created the game takes a set amount of memory.

hope that helped!
