There is nothing about DOS games though. There are releases listed for Windows and Linux even though it's just DOSBOX and the paths are mostly same. I'm not sure what to do especially if GOG did some changes to WIndows version.
It'd be
DOS <path-to-game>\JEDI.CFG
Windows GOG_PATH if it's different
Steam <path-to-game>\Game\JEDI.CFG
