You obviously didn't try it with the Use common V7 encryption because if you had your codes for infinite Gil and max Gil would have read:
Code:
10547F08 0000FFFF
20547F08 05F5E0FF
Do I have to state the completely obvious and point out that it should be turned on for any page of codes that has "Codes compatible for Code Breaker PS2 version 7.0 or higher!" below "Cheat device used"?
