Backward Compatibility

A backward-compatible console, operating system, or service can run software created for an older version of that platform. Support may come from compatible hardware, emulation, translated system calls, or updated game builds. Compatibility is rarely universal: licensing, accessories, online services, unusual hardware features, and technical bugs can exclude particular titles. Enhanced backward-compatible releases may render at higher resolutions, stabilize frame rates, shorten loading, or add automatic HDR without becoming full remasters. The feature helps preserve libraries and reduces the cost of moving to newer hardware.
