My save data for Castlevania DXC and Silent Hill Origins were from 3.40 and when I upgraded to 3.52, they wouldn't load. It works fine when I went back to 3.40. Also, my Metal Gear Solid: Portable Ops savedata appears corrupted when I'm trying to import it into MGS:PO+ in 3.40 but it worked fine when in 3.52. I played MGS:PO in 3.40 and can still play it but MGS:PO+ just can't recognize it. This happens regardless if I am playing with the UMD or ISO version.
Does anyone else have this issue? Is there some sort of weird converter I need or will I have to keep changing back and forth between 3.40 and 3.52? I don't want to go to 3.52 and not be able to play CDXC and SH0 and have to start all over or uses someone else's data.
