IPS Patcher vs MultiPatch

IPS Patcher has no write-up on Specifiction yet; its figures are above.

MultiPatch is a free macOS application for applying and creating file patches. It applies BPS, IPS, UPS, PPF, XDelta, BSDiff, and RUP (Ninja2) patches, and creates BPS, IPS, PPF, XDelta, and BSDiff patches. To apply one, users can select a patch file or drag it onto the application window, then choose the target file and where to save the result. The application identifies the format from the patch file extension, so that extension must be correct. BPS creation offers Linear and Delta modes: Delta patches are usually smaller, but take longer and require more memory. Creating UPS and Ninja2 patches is not supported. The maker says patching is built into the application rather than handled by external tools. Version 2.0 requires macOS 10.9 or later; older releases are available for Mac OS X 10.4 through 10.8. A separate basic command-line version can apply or create patches for scripts or terminal use. The application is GPL-licensed, while the bundled patching libraries have their own licenses.
