disable = false

Equivalent to the '--melonloader.debug' launch option

debug_mode = true

capture_player_logs = true

The maximum Harmony log verbosity to capture into MelonLoader's logs. Possible values in verbosity order are: "None", "Error", "Warn", "Info", "Debug", or "IL". Equivalent to the '--melonloader.harmonyloglevel' launch option

harmony_log_level = "Warn"

Only use this if the game freezes when trying to quit. Equivalent to the '--quitfix' launch option

force_quit = false

Disables the start screen. Equivalent to the '--melonloader.disablestartscreen' launch option

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
