Home › Engine events › Serial bus

Engine executable. Settings and tools of the game program (CivilizationVI.exe), usable without a mod. Mostly undocumented debug and configuration functionality; descriptions come from analysis of the executable and have not all been tried in the running game.

Serial bus
