VBA code help

i need help in buu's fury to put in the gamehark code that i get from the site but for some reason the codes don't work. is their some kind of specific way to put in the code? ive put codes in for the legacy of goku they worked but im guessing the problem is the must be on code.

What version is your Gba game (Buu's Fury)? I mean USA, Euro (might be more than one European ver), or Japan. The codes are for an specific game version.

exactly how did u enter the GS codes that worked. step by step would be nice

This thread is 7 monhts old, so would be btter to don't bump it.

Anyway, to enter the codes manually, start VBA -> "Cheats" menu -> "Cheats List" -> Look at the "Add" section, depending what code you got, in your case click on "Gameshark" -> type the code or copy/paste it, and the description
