prompts = nintendo or xbox (the Button prompts row of the Controls tab, read at start) takes over from pad_layout = xbox_prompts, which is read as pad_layout = nintendo with prompts = xbox. overlay_init loads romfs-patches-xbox for the Nintendo layout and romfs-patches-xbox-label for xbox and auto (input_prompts_folder), loads romfs-patches instead of stopping when the RomFS mods folder replaces one of their files, and the menu says why the prompts in use differ from the setting. The settings probe checks the folder against the layout's button table. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
