IPS Peek is a free, open source IPS patch exploration and testing tool. IPS is a binary patch format commonly used for game patches. Usually, IPS patch files can only be analyzed with hex editors; this can be difficult if the user has no knowledge of the IPS file format. IPS Peek allows IPS patch file data to be easily viewed in a visual way.

IPS patces can be opened, along with an optional target file (a file the patch is designed for). Each patch record can be clicked in a list, showing the data that is written to the file (in the Data View). Patch records can be selectively enabled or disabled for a given target file, and tested with an emulator, all from within the application. Patch report information can also be exported for later use.
