Pacific Fighters v.4.02 (4.02m)

  • Warning

    • The current version 4.02 (4.02m) is not compatible with the previous versions of the sim when playing over the network (Online).
      Both the server and client must have the appropriate versions in order to connect.

    • For your convenience, we have introduced different version numbers for the stand-alone installation and the merged (FB+AEP+PF) install.
      • 4.02 – for stand-alone PF
      • 4.02m – for merged (FB+AEP+PF)

    • Attention: versions 4.02 and 4.02m are not compatible with each other when playing over the network (Online).

  • Patch Installation Instructions (Please read carefully)
    • The 4.02 patch installs only over 4.01 (PF stand alone).
    • The 4.02m patch installs only over 4.01m (FB+AEP+PF merged).

  • Modifications and fixes
    • There is a large number of small modifications and fixes to the entire code of our simulation.
      We accumulated users input and fixed lots of big and little things in order to polish our simulation even further. We sincerely thank all our users who were so helpful in the process!

      • - Added Fiat CR.42’s tail wheel rotation (limited)
      • - Corrected the probability of the FW-190 catching fire
      • - Landing gear breaks easier when skidding

    • Changes to AI:

      • - formation algorithm *
      • - take-off *
      • - landing / taxi *
      • - Bombing in shallow dive for fighters and fighter-bombers (attack aircraft) *
      • - Il-2 aiming with rockets

    • If you have a computer with a Pentium 4 processor, you may occasionally encounter game lock-ups or crashes to desktop. In order to solve that, copy your il2_core.dll into the il2_corep4.dll (for example, with the following command: "copy il2_core.dll il2_corep4.dll"; or, in Windows Explorer, navigate to your sim installation directory, delete the existing il2_corep4.dll, make a copy of the il2_core.dll, and rename the copy to il2_corep4.dll)

    • Corrected the issue on machines with NVidia drivers 72.xx and above, where we had to work around an NVidia bug that caused parts of objects to disappear.

  • Special thanks to the third party creators
    • Skins: Robo and the UBi Skinners forum
    • Armored train: Martin Kubani, Alexey Stepashko (turret) + Vladimir Kochmarsky
