Thanks for the update Arcziii. I can confirm helicopters and projectiles now working. :) The game is running noticeably better now. But for some reason on level 5, I cant seem to blow up the enemy Barracks without the game freezing. I've included my save file. With the previous version it played this level no problem. When the Barracks blows up, the explosion graphic just crashes, and looks like it points to the wrong place in memory for it?
