Hey,
Firstly, TB, great work!
Someone has probably said this before, but here goes:
Here's my take on some of these things:
1. If we can do a JJ1 engine, theoretically, it should be possible to mod slightly and add some functionaliy to make a JJ3D... But I'm getting ahead of myself.
2. Have you thought about using the Jazz1 Raw level extractor to analyse level format? I read somewhere that events are specific to the level, and so are the anims...There are some useful tools in with J1CS.. this is from the help file... maybe it'll help to get the enemies working...
"Each level in JJ1 uses a different arrangement of sprites. So when you set an
animation property in J1CS, what will be shown depends entirely on which level
you are editing.
GetAnims.exe will scan a level and give you a text file describing what each frame
of each animation is. "
D'oh! I just realized, you were part of the J1CS team.. Silly me...

I can probably do some looking at the file format for JJ1 levs, menus, etc, if you want... Just ask....

I can do some good graphics work, so if you want something, lemme know...

I probably forgot something, but anyway, keep the great work coming, and let's keep Jazz1 alive!
