That looks really good. I'm pretty sure with a little imagination and a LOT of time. Someone could make a game similar to alttp. Heck it could even be a cooperative project where one person does one area of the map, while another one does another area.
cooperative in this case means that many people do different modifications in same second and ZOLE is not made for that.
Then how to mix two changed ages roms???
ZOLE can't replace dungeon 1 from (file a.gbc) with dungeon 1 from (file b.gbc) and same for interactions and static objects.
Lets say for example if i make the first quarter of overworld.
Then a another human does the last quarter of overworld.
But then, the first quarter of overworld in my rom is different than the original rom.
And the other human has a modified last quarter of the overworld that i don't have.
Then why is ZOLE not made for cooperative projects???
One person modifies the music and other people modifes other things, everything in parallel.
