It'll be a while untill the next update. Maybe the next update will be the hack's release. I'm now in the long tedious process of planning/preparing/organizing/creating/adding background graphics. I knew this task would be a lot of work but it's more than I expected. And then there will be the same work for the darkworld.
It involves creating the tiles graphics, changing the metatiles in the rom, updating my metatiles image for map editting using PRG editor (it's my precarious map editor but it's what I've got), updating my document so I can keep track of metatiles, changing dynamic depth graphics algorhythms (tiles change graphics automatically depending on how deep the room is in the map, but I'm changing exactly where and how many times that happens), reorganizing some rooms so I can have graphics for the portals, reorganizing gold positions so they don't end up the wrong color by being positioned on top of a green background, and then the usual fine tuning and bug fixing and final adjustments.

mid: my custom table image. each tile is a pixel art I did to represent that metatile. creating this image is a lot of work but now I can edit rooms visually.
right: the result
So, don't worry, I'm working on it and I plan to release it on the 30th anniversary (sept 05). Without any new song unless someone does it. I don't know how to do that.
