I upgraded from 5.00 M33-6 to 6.20TN-C. I started playing the BbS US iso on M33 and decided to upgrade to 6.20TN-C because I got the UMD. Now my saves say that they are corrupted but they still show up in the XMB and when I load the game. This includes the system data, Terra, Ven and Aqua save data I've already tried SaveGameDeemer and FreeCheat+SED and they didn't work out. I don't know if was doing it wrong or what. If anyone could please help me with this, I would be extremely grateful.
