>>But you must have at least 6 pokémon ready to battle or else you might freeze the game and scrap your save since its looking for exactly 6 pokémon.
I suppose N-rage thought everyone would use 6 pokemon (who wouldn't) and also didn't feel it was necessary to fix it.
>>Another bugg would be when you wanna go in gb game from n64 stadium........after save selection it hangs (white/blue screen)
had to learn that the hard way. Thought it was the save, and deleted it. There's really no point if you have VisualBoy in front of you. Don't expect it to be fixed soon.
Just be happy you have Transfer Pak support
