Qt 4.8 和製MESS その６

最後にAndroidで動かす手順をまとめたいと思います。まずは、SC-3000.proをQt Creatorで開きます。「Necessitas Qt 4.8.2 for Android armv5」でプロジェクトを構成します。フォルダ構成は以下になります。

＋SC-3000
　SC-3000.pro
＋src ←和製MESSから上書きコピー。以下のファイルのみ差し替える
  qtmain.cpp
  qt_input.cpp
  qt_screen.cpp
  qt_sound.cpp
  emu.cpp
　emu.h
＋include
  tchar.h
  windows.h

ビルドしてみてコンパイルエラーを消して行きます。
