Okay, so here are the codes I tried.

They don't seem to work, and I would like to know of its just me or the codes themselves.

what emulator is it that your using?

Visual Boy Advanced.
Codes for other games work, but the ones at that link don't.

I just want to know if its only me or if the codes have a problem.

EDIT:
Okay, nevermind, seems the problem was the ROM, thanks anyways though.
