Clones and remakes are created for various reasons, including competition, standardization, availability across platforms, and even as homage. Compatibility with the original system is usually the explicit purpose of cloning hardware or low-level software such as operating systems (e.g. AROS and MorphOS are intended to be compatible with AmigaOS). Application software is cloned by providing the same functionality.
