IPS is an acronym for Internal Patching System. Files that contain the .ips file extension usually store patch updates for ROM image game files.
The IPS files that are used by computer gaming applications may contain the models, graphics and other details that are used to update a variety of computer gaming applications. These provide users with updated and "fresh" game play experiences.
The Nintendo SNES emulator ZNES is one of the software applications that uses the IPS file format for update patches.
The IPS file format is normally only used for small game patches that contain 16MB of data or less.
