After hours of searching, I have finally realized the only way to convert a .psu file (PS2 save) to a .psv (PS3 virtual memory card) to be able to play your old PS2 saves on your PS3 is by using the memory card adaptor.
Unfortunately, my PS2 broke, but I was able to back up my Final Fantasy X save onto my computer. I really want to continue where I left off, but I have no memory card adaptor, and I'm not allowed to buy anything for myself (teenager living with parents).
Could someone be so kind as to convert this save into .psv? I would not want to go through endless hours of grinding again.
And by the way, I DID look at the PS2 save conversion thread that was pinned, but it appears inactive...
If anyone has the means to convert .psu (or any other ps2 game save format) to .PSV and is interested I have about every format possible of my ps2 game save for Castlevania-Curse of Darkness from psx2 that I played on my laptop after my ps2 slim died (piece of junk, but my ps2 fat was stolen).
I just want to finally get to finish this game after trying for so long. I have included the save file from the original disc on my ps3 fat that I saved in case someone can just edit that file to add my save to it with some tool I haven't found online to edit a .PSV file. If necessary I am even willing to pay a reasonable amount of money for conversion through Pay Pal.
