The Galaga++ project was a school group project. The group consisted of eight programmers, tasked with creating an altered form of the classic game "Galaga" using C++ on a custom, group developed engine. I have pasted some code below from one of the classes I wrote in collaboration with another member of the team, which displays the game's credits:
//--------------------------------------------------------------------------------------------------------------------------------

myPlayField = CRECT( 0, 0, winWidth, winHeight );
std::string filename = DxAssetLocator::instance().getConfigPath( "newSpriteSheetDescriptor.txt" );
//SAS: This and its ilk likely near to the 1st thing to occur in gameInit
bool assetsLoaded = AssetManager::instance().loadAssetDescriptions( filename.c_str(), app.dxDev() );
