I cannot figure out how to create my own grifballl variant for Halo Reach. I was able to add the grifball maps and gamemodes by going into the hopper_game_variants and hopper_map_variants and copying the griffball maps and gamemodes and pasting them into my mods folder.
When go into the custon games, load a gamemode and make a few changes and save it as a new gamemode, The newly created gamemode will not show up the next time I boot up MCC.
Is there a way to create your own gamemode variants from unique gamemodes like grifball?
