メモリダンプタイプ B 作成中っぽい何か。４
一筆書きですが動くようになりました。
ダンプモジュールの状態遷移部分は見直ししてみたら結構書き直さないと駄目そうです。
日曜日くらいまでに本ちゃんの方に統合できれば良いかなーと思ってます。
毎フレーム、ユーザメモリ全てを最初から最後まで逆アセンブルし、そのうち表示すべきアドレス16行分のみ
画面に逆アセンブル結果を表示するようにしてます。
GMC-4 専用な書き方してます。妥協です（苦笑）。
逆アセンブル用に読み込んでるプログラムは
GMC-4 を入手して間もない頃に書いた簡易スロットゲームです。
C 言語用配列データとして別途読み込ませてます。
