How would it be possible with bigger dungeons? I've looked in the editor and found only 2x256 screens of indoor/dungeon in seasons. I know that both ages and seasons only use like 2-400, but are you saying its possible to increase that?
Assembly hacking and table expanding. Things that would be hard to implement with ZOHS but easier done manually. I'll see what I can do. It's possible to increase anything, but you have to have assembly knowledge to reconfigure the code to load the table at a different location and maybe differently. ZOLE and ZOSE applied patches that did this a lot.
I have to tell you, I had a similar idea. Not that all four maps would be different areas of the same world, but that (using a Seasons ROM and mechanics) each "season" would be much, MUCH different than the others. Obviously the "stump" would be in the same location, but other than that, the worlds would be similar in the sense of large landmarks (mountains for instance), but the forests and beaches and plains would all be different. There would be unique towns for each and NPCs would talk about their town or local area.
If you're interested, maybe we could talk about my idea (I've got a rough story for it, but I'm going to keep hush on that until I've actually started working on it and have some mapping done).
Perhaps, perhaps. I wouldn't be able to map stuff alone and from what I've seen you're great at it
