runtime/menu_assets.c reads them from the user's RomFS at runtime (nothing is shipped): .zs files with the dictionaries of Pack/ZsDic.pack.zs (streamed when a frame does not say its size), the fonts of Font2/Scalable behind their 8-byte header and per-word XOR key, and BNTX textures (Switch 2 archives say "Ounc" where Switch ones say "NX ") through the runtime's block-linear copy and BC4 and ASTC decoders. ui/menu_art.cpp decodes the shared interface archive on a worker at the first present and uploads each texture for Dear ImGui at its first use. The menu now uses ClarimoUDPE for its text (with a sixth more line height) and CetraDisplayPro for its title and tabs, Roboto merged behind both; umber, brown and gold colours; the game's ornamented frame along the window's edge (the art holds two sides and is drawn again turned for the other two); its cursor glow and line around the selected row (edges only, so the label stays readable); and its control-guide bar under Continue and Quit. Without the files it keeps Roboto and plain shapes. The window's pointer is an original gold arrowhead drawn at start for the system DPI.

Opening and closing the menu, moving the cursor, changing a value, pressing an item, cancelling a dialog and changing tabs play the game's system sounds (Plus menu open and close, cursor, decide, cancel, tab move), read from the user's RomFS at the first use and decoded from BWAV (DSP-ADPCM or PCM16, 48 kHz) in runtime/menu_sound.c. They are mixed over the game's output in the audio callback with up to eight voices started without locks. The Sound tab gets a Menu sounds volume (menu_sound_volume, 0 to 100, default 80, under the output volume). A RomFS without the files stays silent.
