However, all PlayStation 3 models can play some PlayStation 1 games via physical discs. Initial PlayStation 3 models released in North America, Japan, and Asia contained both the PlayStation 2's CPU and GPU, while subsequent models contained only the GPU, and the PlayStation 2 backwards compatibility with physical discs was removed entirely in later models. This is a list of PlayStation 2 games compatible with certain models of PlayStation 3. This list is incomplete you can help by expanding it.
