The program creates a copy before you start fs9.cfg and replaces it with a member selected from the list. Written by me to start MFS9 with different settings for different scenarios of aircraft and the like. It is also possible bystoroy settings: TERRAIN_MAX_VERTEX_LEVEL and PAN_RATE. now an improper request dll or bpl etc. (PAN_RATE now works with an increment of 50) became smaller. Added buttons open a configuration file for manual editing. Added button to start the Active Sky, added the ability to quickly edit TEXTURE_BANDWIDTH_MULT, UPPER_FRAMERATE_LIMIT, TextureMaxLoad, TERRAIN_DEFAULT_RADIUS, TERRAIN_EXTENDED_RADIUS.
