+* WirelessChecker - 本体デバッグ用 無線機能チェックプログラム
+
+- 確認手順
+
+1. 本体無線フラグの確認
+
+   上画面の「無線ON/OFF設定」および「無線強制OFF本体」の設定を確認してください。
+   無線が使用できる状態は、以下の状態です。
+
+   無線ON/OFF設定[ON ]
+   無線強制OFF本体[No ]
+
+
+2. DS無線の初期化テスト
+
+   DS無線の初期化→スキャン→終了をテストします。
+   アクティブスキャン(電波を出すスキャン)を行います。
+   LEDの点滅を確認することで無線が正常に動作していることを確認してください。
+   また、無線ON/OFF設定をOFFにすることで、初期化が失敗することを確認してください。
+
+3. TWL無線の初期化テスト
+
+   TWL無線の初期化→スキャン→終了をテストします。
+   アクティブスキャン(電波を出すスキャン)を行います。
+   LEDの点滅を確認することで無線が正常に動作していることを確認してください。
+   また、無線ON/OFF設定をOFFにすることで、初期化が失敗することを確認してください。
+
+4. FATALエラーリカバリテスト
+
+   TWL無線モジュールのファームウェア壊れをエミュレートし、それによるFATALエラー発生後、
+   アプリジャンプによるハードウェアリセットで、ファームウェアがロードし直されていることを確認します。
+   再起動後に自動的にTWL無線の初期化チェックを行います。初期化チェックが成功し、LEDが点滅していることを確認してください。
+
+（以下の項目はオプションです。）
+
+5. FATALエラーエミュレーション
+   項目4.のFATALエラーを手動で起こします。この操作を行った後、「TWL無線の初期化テスト」が失敗することを確認してください。
+
+
+- TODO
+
+・NOAとかのデバッグにむけて英語表示も対応（？）
+
+- 変更履歴
+
+- 080801
+  NANDアプリに対応。
+  バナー追加。
+  ゲームコード追加。
+
+- 080731
+  FINALROMでビルド。
+  テスト用のプリントデバッグが出ていたのを修正。
+  コマンドログを日本語化。
+  TwlSDK 5.0 RC1でビルド。
+
+- 080730
+  下画面に簡易ヘルプを表示。
+
+- 080725
+  最初のリリース
+
