OVGME
OVGME is a popular modding tool for DCS that allows you to selectively enable and disable mods individually, by saving them in a seperate folder and only linking to this folder when a mod is enabled in the program. This allows you to quickly disable mods in case of an Integrity Check failure (for a particular server or due to a DCS update), as well as diagnose and disable broken mods.
Sadly the original developer Sedenion is no longer developing this extremely useful tool, but a few people are hosting mirrors of his original work and some are even attempting to further develop this tool: as of DCS 2.5 the tool is still compatible with DCS and as such you will find all manner of guides and information on this page to help you make the most of OVGME with DCS.
