This is for anyone who is interested/has 4.21.1 REX CFW. This is a list of my own personal games and the settings that I have on them. These games were all updated through the PS3 to the latest official patches and are untouched nor have they been modified in ANY way.
The games have their original EBOOT and PARAM's. Also, when I updated to 4.21.1 REX I reformatted the HDD in my PS3 so I could start from scratch. I have encountered no problems at all with these configurations. I tried to put as much info as necessary to help out.
