Mauron, when you say foreground and background--which is the layer that the sprites should move about on? I could see it being either, depending on the situation.
Here's a PNG. This is all on layer 1. As soon as the party moves into this location, they are locked in place.
Cherenkov: This is a pretty vanilla hack for the most part. But I've cleaned up the text, expanded some scenes, added more of the party members talking back and forth depending on who's in the group, put in a few new techs, added a few locations, there's some new weapons, etc.
The coup de grace (and what I'm working on right now) is a quest in 12,000 BC to rescue Schala. Someday, I'd like to do a 2.0 of this hack where Schala is the 8th playable character.
I don't know if you're familiar with my Playable Golbez Edition or General Leo Edition hacks on romhacking.net, but this is basically the Chrono Trigger version of that. Like, the 1995 Woolsey release, cleaned up, and updated with new content that the 15 year-old me wished for back then.
