IUBPatchLib
What it is
IUBPatchLib is a C++ library for applying binary patches, with ROM hacks among its intended uses. It supports IPS, UPS, and BPS formats and provides an API based on RAII and move semantics. The core library has no external dependencies and works on Windows, Linux, macOS, and other POSIX systems. Optional memory-mapped I/O is available for file processing.
Developers can build shared or static libraries with CMake and connect the project through find_package, pkg-config, or FetchContent. The included iubpatch-cli can apply patches, show patch details, and validate patches. Patch options include checksum verification and backup creation. The build configuration enables tests and command-line tools by default, while examples and benchmarks are disabled by default. IUBPatchLib 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.
