How do I use Gameshark/Codebreaker cheats on VisualBoyAdvance (Emulator)? - visualboyadvance cheat

I'm playing Harvest Moon: Friends of Mineral Town in the emulator. I found the code, but when I try to put him, says: "WARNING: The codes seem to be from another party. The codes can not function properly."

Who knows why this happens and how can I solve this problem?

Thank you in advance.
