Stuck at Floating Continent

It could be an event freeze. But to exclude a zsnes issue, I would suggest testing with a more accurate emulator such as SNES9X or bsnes and without the optional patch (just have a 2nd ROM and copy/rename your savefile to that new ROM name). These things are more or less not likely to be the cause but we never know. Maybe Gi Nattak can test the event when he see this..
