Ocorina of Time with gameshark 3.0 problems

I can only get the '(M)' "must be on" code to work with zelda v 1.0. If i enable any other code the screen will stay black. Can anyone help me?
I also changed the "must be on" code to another one i found and now it won't load with that on. Can someone give me the correct must be on code?

thanks

 

found the "must be one code" looked at v 1.1 for zelda
still can't get any others to work

 

Turning the code generator on help?

 

forgot to turn on code generator.
It works fine now.
Thanks

 

Code generator is only used to find code, you should don't need to put it on to make code work, also preloaded code should work, are your sure that you have an v1.0 OOT (Gold cart in US)?
