Set the plugin's Controller Pak to Transfer Pak, select the GB rom and then select the corresponding save file. Start Pokémon Stadium and work from there.
Okay my he recognize my game. But you have to play it on the gba-emulator because it's not possible at the pj64 emulator? So you ca just use the pokemons from you gameboy rom but cant play on the game. Is that right?
edit: When i start the pokemon gold in pokemon stadium2.. i just get a white display
