I've experimented a bit with overworld cutscene editing, and I've found something... not spectacular, but which hopefully could still be useful. From a location, it shows the world map then returns to a location (not necessarily the same one). I did this with the 600 AD map, but there are probably similar codes in the other eras.
In the location events, put this where you want:
- BitMath 7F01F8 Bit 1 Set
- Change the location to {1F1} Middle Ages
When triggered, this will switch to a view of Hero's Grave on the world map, then teleports the party to the End of Time (I think normally this scene plays when Gaspar tells you about the Cyrus side-quest). If you don't put a ChangeLocation, the scene will still shows when you walk out of the room.
To change the scene (just a bit), you can do this:
In the Middle Ages overworld events, look at [0B0A] (look at the attachment also):
- 7E00E3 and 7E00E5 are the X coordinate (one for Layer1 and one for Layer2)
- 7E00E7 and 7E00E9 are the Y coordinate (one for Layer1 and one for Layer2)
- [0B2C] is the duration of the scene (in whatever unit of time)
I have no idea about the other commands, and no idea about how to put sprites in the scene (I've looked at the scene in 2,300AD with the scrapped Robo but the code is much longer).
I hope I'm not stating what everybody already knows or something.
