I've been decoding the Sh5.exe and it's support files for over 2 years now
The map markings are not saved to any file in SH5. I have the code bookmarked where all the map tools are 'made' and updated.
Ultimately I will add code that will save all the map tools to a file (at Career game end) and load them from the file (at Career game start). Right now I'm busy fixing the carriers not spawning aircraft in the game
Found the SH4 code for the scout aircraft. The devs 'RET' it out in SH5 (any function dealing with scout aircraft has been replaced with RET - return to caller thus being disabled). How did these scout aircraft work in SH4
