Codes/Cheats fail to start on SSBB

Neither US or UK codes will work for my Brawl ISO. They either fail to load at all or cause the screen to go black when loaded. This is very frustrating for me as even the gecko codes don't work severely limiting what I can do with brawl and it's frustrating me.



Example Codes:

US Unrestricted Camera:
000A7D60 4E800020
00109D88 38800001

This code causes my game to crash when it first loads, leading to nothing but a black screen.




I'd like to know if the codes I've been getting are bad, if the ISO is bunk or if there's something else I'm missing.


And yes CHEATS ARE ENABLED.
