@Kyotoo and tr4nquility:
Looks like those games share a common issue. They're attempting to use the wrong version of PRX decryption. I'll have to look deeper into this, but atleast for Dissidia this should be easy to trace and fix. Unfortunately, K-ON is probably using a new encryption method since it belongs to firmware 6.31. All games after firmware 6.30 are using a new encryption mechanism that still haven't been figured out due to the inability to analize the new firmware modules, which are now ECDSA protected.
