If you edit files inside of a DCS game program folder (usually C:\Program Files\Eagle Dynamics\DCS…), files edited will be overwritten on DCS update. It might be frustrating, if you have to edit .lua files back to your settings after every update.
For this problem, you can use OvGME to add edited files as “mods” into a game. You can familiarize and download OvGME e.g. from https://wiki.hoggitworld.com/view/OVGME
First create a folder for mods. I have used Windows normal \Documents folder under my user profile and created there an OVGME Mods folder:
Install OvGME and check correct settings. Title is just a name for used configuration. Root folder is a DCS game folder. Mods folder is folder for mods that we just created:
Then see for where your edited .lua files are in DCS game folder and create the same structure into your OvGME Mods folder.
For IFEI and UFC edited .lua files, create folder and add .lua files to:
…and for kneeboard position .lua file, create folder structure and add file to:
Restart OvGME and you should see in OvGME a “Hornet View lua edits” folder mod that you can select and enable:
You can quit OvGME and your mods are still enabled. To disable them, you have to start OvGME and disable them.
Remember to disable and enable your mods after update (or better disable before update). They will not work after update.
