'ello.
Was a really long time since I last logged in here. (not playing JJ2 anymore, but still have love for the game)
I just happend to step by today looking for JJ2 music and saw this thread, so I thought I might share the Razz Arena source code which I got from Piet a really long time ago.
I hope you don't mind if I share it..?

I did some maps and some small improvements for the weapons and textures, but it seems to have been lost over the years.

If you are interested and serious about continue the development I might join up.
