Advanced Settings
Power user features, experimental options, and developer tools.
Advanced settings unlock experimental features, debugging tools, and fine-grained control over launcher internals. Only modify these if you know what you're doing!
| Setting | Type | Default | Description |
|---|---|---|---|
enable_experimental_features | Boolean | false | Enable beta/experimental functionality. May be unstable. Great for testing and providing feedback! |
check_nightly_updates | Boolean | false | Check for pre-release nightly builds instead of stable releases. Get newest features first (with potential bugs). |
default_memory | Number | 2048 | Default RAM allocation in MB for new installations. Can be overridden per-installation. Modern modpacks: 4096-8192 MB. |
separate_logs_window | Boolean | false | Open game logs in separate window instead of integrated tab. Useful for multi-monitor setups. |
auto_save_interval | Number | 30 | Auto-save launcher state every N seconds. 0 disables auto-save. Prevents data loss on crashes. |
show_advanced_page | Boolean | false | Show the Advanced page in sidebar navigation. Contains symlink management and debug tools. |
extra | JSON Object | {} | Free-form JSON object for custom key-value pairs. Used by plugins and extensions. |
Experimental features can break at any time! Always keep stable backups of your installations before enabling experimental mode.
