I'm not sure if this is present only in dungeons but it has happened to me both times in one, one time as I was about to fall into the boss's lair in dodango's cavern and another as I fall into one of those whirling holes in Jabu jabu's belly to follow princess Ruto. It doesn't give me any error messages, the whole game just freezes, the v/i counter is still going from 59-60 and I can still end emulation and exit out or play another game no problem. Anyone else have this prob and suggestions?
