Multiplayer

In the multiplayer modes, you can use either a Link Cable or a pair of Wireless Adapters to connect the GBAs. The communication device is autodetected.
When using a Link Cable, the console with the 1P end of the cable will be the host. The host always selects the song.
- If you want to force the cable mode, hold L before entering a multiplayer mode (the screen will display: Connecting... [cable] instead of the regular message).
When using Wireless Adapters, the consoles connect to each other automatically.
- If you want to play as host, hold R before entering a multiplayer mode (the screen will display: Connecting... [wireless / host] instead of the regular message).
- If none of the players uses the R button, a host is randomly picked.
Any player can abort a song by pressing A+B+START+SELECT.
Any player can exit multiplayer mode by pressing SELECT.

VS mode

In this mode, the players battle against each other. The one with higher score wins.
If both players die, a Stage Break will be triggered.
The game will indicate at all times who is winning by making the winning player's life bar bounce.
The host and the guest can opt to play in different difficulty levels. In that case, the evaluation will change:
- Same level: The judgement is based on points. If one player dies, it stops adding points.
- Different levels: The judgement is based on dance grade percentage. Dying is not relevant in this mode.

In this mode, the players play together a Double chart and share the score.
Multiplier changes are shared.
Playing this mode is the only practical way of winning the charts labeled with ;), as these are exclusive co-op charts.
