Worries about animations and start positions are for a later project. I do want to make another program that'll get you playable JJ2 levels with only a little input (mostly along the lines of confirming its guesses about which events you want to use), but I don't know any GUI code yet, so that's going to be a bit later down the line. This is just for people who would rather edit level layouts (but not events, animations, background effects, etc.) in JCS than J1E, so all I have to be able to port back and forth is layout, tileset, mask, and event names.

ETA: Transparency and layers 5 and 8 are good to go. So is masking but you can't see that here.

I'll stop posting screenshots and let discussion of the actual topic resume now.
