IPS Patcher vs IUBPatchLib

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

IUBPatchLib is a free modern C++ library for applying binary patches, with ROM hacks as a stated use case. It supports IPS, UPS, and BPS formats and works on Windows, Linux, macOS, and other POSIX systems. The API uses RAII and move semantics, while the core library has no external dependencies. Developers can build shared or static libraries with CMake and integrate the project using find_package, pkg-config, or FetchContent. Optional memory-mapped I/O is available for file processing. The included iubpatch-cli can apply patches, display patch information, and validate patches. Patch options include checksum verification and backup creation. Tests and command-line tools are enabled by default in the build options; examples and benchmarks are disabled by default. The project is released under the MIT License, which provides the software as-is without warranty. The maker invites contributions through issues or pull requests and says changes are reviewed when tests pass.
