Saxman wrote one years ago when he offered only the MKVIII with 125Mil glide bombing stadia ramp to unzip directly into your sights folder. The association was to about 12 aircraft. The NAVY had 4 versions of the Mk8 reticle.
It's a long process creating it all after the long process of researching it all. To create the kind of the zip package you are asking for. You have to edit all of the <aircraft name.txt> files in the sights directory, and add the name of the <gunsight.bmp> file. Then you package all of those along with all of the <gunsight.bmp> files. And in my case <gunsight.mil> size control files.
Somewhere about 300 files. We have a lot of aircraft now.
I have no interest in helping anyone drop 300 flies in the wrong Aces High directory by accident. It got a bit mind numbing the last time around updating the <gunsight.mil> files and updating existing bitmaps while adding new bitmaps to it. Just the Cyrillic language translation research to get the reticle for the 1930's era PAK gunsight in the I16 was mind deadening.
My historic pack has readme text files in every country folder giving you the reticle to aircraft associations. That way you are only copying a few files at a time. Less to go wrong.
Chances are this forum is seen by less than 5% of the player community in the game. The only reticle(gunsights) many players are ever aware of are the default from HTC. Or those personal super secret favorites passed to them by friends. I will venture the most commonly used is a single dot, while I'm considered a tad eccentric for bothering to create historic reticle that for some only clutter their view.
Hey at least you get ww2 gunnery manuals for free in my package.
