When it comes to GB and GBA databases, this happens when you are using a hack. The Code value is generated based off the ROM's header ID, so that the code values are consistent among different people when it comes to using Local Multiplayer.

In short, the database already has a Pokemon Leaf Green in its list. The first one is most likely a hack, so you should change its Code value or change the hacks Game ID in its header to something else.

I have just made a clean database didn't seem to be a hack(pokemon leaf green). My databases were just not doing good with CaVE. Pursuing clean database has resolved my issues.

Made a new database seemed to fix
