**BGM・効果音
-&color(red){雛形２}を使用します。
-短形波・三角波・ノイズの設定と再生を行います。
-STARTを押しながらSELECTでタイトルに戻ります。
-各項目で左右を押すと値が増減します。
-SHUHASUはSELECT・A・Bいずれかのボタンを押しながら左右を押すと増分値が変わります。
-SHUHASUには以下の内容を設定します。
--矩形波：1790000/ (周波数 * 32 - 1) ・・・「ラ」（440hz）を鳴らそうと思えば127になります
--三角波：1790000/ (周波数 * 64 - 1) ・・・多分。
-STARTを押すと音が鳴り、フラグの内容が16進数で表示されます。&br()ゲームを開発する際にフラグとshuhasu、timeの値を指定すれば同じ音を鳴らすことができます。
