Are you sure the EU version is censored?

No.

I searched internet for a significant time and cannot find anything useful.

Only found a web page for God of War (first one), which says that EU version is censored stupidly.

So, I just speculated that might be the case for every greek saga games.

Also I just came to know that there is a ENTIRE fandom page dedicated for censorship.

Looks like Brave search got a lot of room to improve.

Thank You for the help.

It’s playable. Not at very good state though.

I didn’t. I just extracted the ISO like any archive.

Can you provide any good guide for decrypting ROMs, please?

I tried all of that. In EU it increases performance. But US not works.
