# Nightmare Creatures: PlayStation executable analysis and native PC port

> Nightmare Creatures ports the USA PlayStation game to macOS, Windows, and Linux using a user-supplied CHD image. Its runtime interprets the original processor code while native components handle graphics, sound, input, and saves; separate tools analyse the game's executables and progressively translate code into C.
