Well I have successfully downgraded a 6.20 TN PSP 3000 to 5.03 CFW. It was another one, not the one I was asking about in a different topic. The problem is I have made some good progress in a few games on 6.20 TN, specifically GoW Ghost of Sparta, Split Second and others. BUT OH, HORROR!!! The PSP now (on 5.03 GNE-C) does not recognize my saves and says they are corrupted. Am I totally screwed i.e. do I have to start the games over? I've read some info about re-encrypting those saves but that seems rather high-level for my simple user's mind. Would appreciate if anyone could help, or shed some more light on this.
