Builders and tools
Engines to make your own games, emulators to preserve old ones and chess engines to train with. Not games to launch, but the foundations the rest of the library stands on.
About emulators: Emulators are legal software. BIOS files, firmware and game ROMs belong to their makers, so use only copies you own.
