Overhaul
d8145755c3
Replaced Windows console with freeware console implementation. Activate in windowed mode with \ Added error and quit if JA2 started in window mode in >16bpp color depth Fix to enemy sector investigation: Was deducting from redshirts when elites investigated Fix AWOL militia (need additional fix to prevent them from being redistributed during after reinforcements) Fix to tanks to add them in their original spot when a new one cannot be found. Should modify to remove old wreckage in this case. AI no longer tries to fire mortar when no room for it Tanks no longer try to throw knives git-svn-id: https://ja2svn.mooo.com/source/ja2/trunk/GameSource/ja2_v1.13/Build@1030 3b4a5df2-a311-0410-b5c6-a8a6f20db521
