Description

This menu edits a temporary copy of the settings. Existing values are changed only after the user selects Save and exit or Save and start. Exit without saving discards the temporary copy.

Available settings

Setting	Examples	Recommended behavior
`LOADER_TYPE`	Fabric, NeoForge, none	Use Fabric first; use NeoForge when a required mod needs it.
`RAM_INITIAL`	2G, 4G	Leave memory for Windows and other applications.
`RAM_MAX`	4G, 6G	Do not assign all physical memory to Minecraft.
`GUI_MODE`	gui, nogui	Use `nogui` for a lighter dedicated server console.
`GC_PROFILE`	default, low-pause	Start with the tested default and measure before tuning.
`ONLINE_MODE`	true, false	Keep `true` unless a trusted authentication proxy is documented.
`AUTO_CONFIGURE_JAVA`	true, false	Only changes the current user's Java environment when enabled.

Safe workflow

Open parameter-manager.bat from the repository root.
Choose each setting and follow the validation prompts.
Use Save and exit to return to the launcher, or Save and start to continue.
Use Exit without saving to cancel without changing the previous configuration.

Online mode: Setting online-mode=false is unsafe on a public server without a trusted authentication proxy. It is not a normal Floodgate workaround.
