Deon FoucheandClaude Opus 5.5 50f7f5a86c Pick the button prompts with a setting of their own, matched to the pad layout 
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.
