what about the installation? I see there is also a Pacific Islands map, what to do with it?

Read the instructions above. I did have some problems with posting in here.
Tweaking Uberdemons mission generator, MM and DCG to work with my map:
1. Go to:Ubisoft\IL-2 Sturmovik 1946\MODS\MAPMODS\maps\ in your computer and rename net8island folder to ;net8islands.
2. RenameUbisoft\IL-2 Sturmovik 1946\MODS\MAPMODS\maps\Kt_channel to net8islands and thats about it.
Launch IL2 and open quick mission builder, select plane/s and pacific islands map. Hit fly and if you are in channel everything is alright!
DCG : open DCG and create new Pacific 42 campaign either for RAF or Germany. Go to squadron Editor and change the planes and units to fit BOB . You can edit columms and ships too. There aint not much ground activity, so its mainly dogfighting, escort missions and naval targets like in real BOB!

If you know the basic FMB, you can edit pacific 42 master mission in FMB. You find it in your DCG folder under Data\masters\pacific 42. Copy it to IL2 missions\whatever folder and you can add more ships and buildings to master template. When you done save your mission and close IL2. Go to IL2sturmovik\missions\single and copy pacific 42.mis and paste it to DCG\dat\masters folder
Start to play and have fun while waiting patiently REAL BOB maps!
