Unfortunately I think that's a bit over my skills (i.e. OpenGL 1.1 without extensions nor shaders is my top skill right now). Also I'm quite focused in Allegro.pas that needs a lot of work too (I think it is limiting my skills, but I promised I'll do it, so I must do it).

Anyway I like to see a professional engine written in (Object) Pascal. We had Gamecask but unfortunately it looks a bit dead now.

I really like to help but I don't know how. Please let us know when you have something.
