Hello, I'm a PS3 user who just bought a Korean PS3. As you all know, asian playstations have switched o and x buttons and ot is unchangable. I found it disturbing and I've searched around the internet to find some infos and I found out that it can be changed by editing xregistry.sys file. What I couldn't find out was how to get access to this file(my PS3 is on unexploitable firmware). Is it just simply impossible?
