What about if Chupa taught us to fish instead of giving us the fish?
These air.inis are packed, by date, as JSGME Options for ease of use. - Excellent!
Glad you like it, there are some points I would like to highlight though.
Lets take for example, 1942-1945 and how I come up with it.
I searched
plane.properties for planes that have 1942-1945 in description and copied only those entries.
It was done using automated tools in Notepad++ so it took seconds.
He-111H-12 He 111 H-12, 1942
Bf-109G-6_Mid Bf-109G-6 Tall Tail, 1943
P-51D-5NT P-51D-5NT, 1944
SpitfireF22 Spitfire F.Mk 22, 1945
...For example.
This step gave me planes for particular time period.
After this I used other tools to separate first entry of every plane
Bf-109G-6_Mid from not needed now, second part
Bf-109G-6 Tall Tail, 1943 Of course it was done automatically and not manually so, again, it took me mere seconds.
I had to do this step because I needed a list, only one plane per line and without additional spaces, tabs and everything else.
In the next step I used entries I got and added them to spelling dictionary word list in notepad++
I did this because there were tools to find differences but I couldn't find tools to find similarities so I used spell-checker.
After this I opened up air.ini and enabled spell checker.
As a result it highlighted only those planes that weren't in the entries added which means everything 1936-1941 and 1946-1955.
Which I had to delete manually but since it was already highlighted it was easy and fast.
Here is an example how it looks to me, just delete everything in red and you good to go.
Looks like a lot but in practice, it takes minutes to set up what ever age period you want.
With this solution you have planes released to service in 42-45 but, it doesnt contain planes from 40 or 41 which would need to be here if I was making a war theatre.
So, if you are looking for actual theatres, its better to use US&UK/Soviets vs Axis, Pacific Theatre and Stock game air.ini.
Air.ini segregated by year is just for more diverse planeset in QMB and for people who like to play on-line with friends on private servers.
