Kingdom Hearts Birth by Sleep Final Mix

[VIRGIN KLM]

For some reason I can't start or load a game, it just leads me to a black screen that nothing happens and TAB and Start won't help.
Also I noticed that the unencrypted dump from my UMD doesn't proceed the first (invisible on PPSSPP) red box with the data that being saved on the MS, pressing O just loops again and again which is the same thing that happens when it says that the gamedata is corrupt which happens also when you fail to decrypt PGD. Only the unencrypted iso with the English translation works which leads me to think that PGD decryption has some bugs/flaws that haven't been noticed so far.
