PS2 Save File Transfer

[Rennikz]

i have Onimusha Blade Warriors...only bought it because it was a 4 player and to get one last character i need to have a saved file from onimusha 3 so i was wondering if i could use an emulator get the save file and transfer it to memory card
if it's possible how do i go around doing so? do i need a program on my flash drive that can trick the ps2 into thinking it's a memory card? or do i need some special hardware?

You can only do it with Maxdrive.
