Just wondering, does the Demoville demo of JA2 work with either of the fan mods Straciatella or 1.13?
Mainly because the enemy turns take unusually longer than they do in the final game when you play them normally.
One thing I have noticed is an AI behaviour that seems to be cut from the final game, where they can Interrupt you while you are trying to shoot:
&t=20m17s
Can be seen at 20:17, I can't recall this AI behaviour in the finished game.
