OK, first of all I have a win7 Pro machine.. Under programs I made a folder named it PTO and copied all files from SF2NA. In that folder made a copy of NA.exe and renamed it to PTO.exe. Ran the game , and it created the PTO folder under saved games. Deleted all modern aircraft and added all WWII era planes. Applied the weapons pack II , all weapons do show up. Added the nations and formation ,sounds,effects..ect under the saved games PTO folder..Added the Okinawa terrain under the terrain folder under saved games..OK here is what I get…Used a Zero to launch from a carrier…Zero fell through the deck and exploded…most carriers are so dark can’t see details…Helicopter show up when using US planes…Tried B-17 from land base..Only 2 B-17s on runway , but best of all, when bring up the message window,game freezes..Anyone have any clue ?
