**Required game files**: the v0 base NSP. No update is needed.

## Touch controls built for rhythm games

- 👉 **Right half is A**: tap anywhere on the right half of the screen. A glow at your finger shows each press.
- 👈 **Left half follows the level**: it becomes the button that the level needs, such as ▼, ◀, ▶, or B. Levels that need several directions show a small glass D-pad instead.
- 🫧 **Fewer buttons on screen**: B, −, and + are always available. Y and X show only in the levels that use them. The buttons cover less of the picture.
- ✌️ **Multi-finger input**: press both halves at the same time. A very short tap still counts as a full press.
- 🪄 **BeatSpell**: the left half steps (B), the right half attacks (A), and the D-pad, X, and Y also show.
- 🥁 **Drum Lessons**: a full virtual controller with the D-pad, A, B, X, Y, ZR, −, and +.
- 🐰 **Rhythm Toys**: in Who's Got Rhythm? and the sound boards, tap an item to select it, and tap it again to confirm.

## Menus by touch

- 📋 **Direct menus**: tap menu items, lists, and the pause menu. Every visible row of a long list can be tapped.
- 🗺️ **Level map**: drag the map left and right. Tap a level to select it, and tap it again to start it.

## Picture, sound, and performance

- ✨ **Ambient border glow**: the letterbox borders glow with live colors from the edges of the picture.
- 🔍 **1080p rendering**: the game renders at 1920×1080.
- 📱 **iPad layout**: on iPad, B, Y, X, −, and + move into the letterbox border above the picture.
- 📺 **TV or handheld mode from the audio output**: Bluetooth, AirPlay, and HDMI audio switch the game to TV mode, which offers latency calibration. The built-in speaker and wired headphones use handheld mode.
- ⚡ **Faster BeatSpell**: the battle scenes skip unnecessary GPU waits. In a Mac test, the work per frame dropped from about 14.6 ms to about 9.5 ms.
