- PortabilityLayer: A static library that supports interaction with various vintage Mac-specific formats and API calls. Some parts are capable of running by themselves, others require the support of drivers.
- CompileShadersD3D11: Compiles D3D11 shaders into C++ files containing the compiled shader data.
- ConvertColorCursors: Extracts color cursors and icons from the application resources and dumps them to .CUR and .ICO files. Required because Windows has no API for creating color cursors at runtime.
- hqx2gp: Converts BinHex to .gpr, .gpd, and .gpf (resource fork data, data fork data, and Finder data, respectively)
- FTagData: Copies a data-only file to a .gpd and creates a .gpf for it
- PictChecker: Experimental app that extracts all of the PICT resources from all of the houses and dumps them to PNG. Used to verify that the PICT loader works.
