接続するキーボードが日本語キーボードか、かなキーや英数キーがないUSキーボードかによって違うIchigoJamのファームウェアを使います。 日本語キーボード対応IchigoJamにUSキーボードを挿すと、記号などがキーに書いてある通りに打てません。 今回、1.3.2β12で対応した拡張API（BIOS的なもの）を使って切り替えできるようになりました。
IchigoJam 1.3.2β13以降でのみ動作します。
「ichigojam-1.3b13.zip」
内部変更：ROM内のデータ並び位置を変更、修正：画面右端に白い線が入る不具合を修正
こちらのプログラムをUSBシリアルで流すか、打ち込むかして、実行すると画面が一瞬点滅して、USキーボードへの書き換えが完了します！ 本体やEEPROMに保存しておけば読み込んで実行するだけ、簡単です！
