Cゲームボーイの別個の機能がメインファイル

-1

私はクラスアジテーションのためのゲームボーイプロジェクトに取り組んでいます。別の「機能」ファイルと「メイン」ファイルを用意する必要があると言われました。私はこれをやって狂っていくつもりです。私はヘッダーファイル "myLib.h"を作成しました。そこには、 "myLib.c"にある関数の定義とプロトタイプが含まれています。私のメインファイルでは、 "myLib.c"の関数を呼び出してコンパイルしますが、動作しません。 "myLib.c"をmakeファイルに追加しました。ファイルは以下の通りです：Cゲームボーイの別個の機能がメインファイル

"動作しません"を定義してください。 –

何が問題なのですか？より具体的にしてください。 – tobier

エミュレータの画面は灰色で、メインのコードが実行されていないようです。私はデバッガを試してみても、それを壊すことさえできません。 – Reid

私は行がありませんでした。REG_DISPCTL = MODE3 | BG2_ENABLE;
