I never played four swords! I was hoping you can control all 4 links without needing to be multiplayer. As for the Link to the Past portion it's funny you mentioned the game had minor fixes. That was mentioned last night durring a speedrun session. They were talking about tricks speed runners do in the original game that can't be done in later versions such as this one. I don't remember the specifics but it was games like this that did have minor changes to fix glitches found in the originals.
