In their own words
IUBPatchLib
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.
Rom Patcher JS
Rom Patcher JS is a free tool for applying and creating patches for retro video-game ROMs. It runs in modern web browsers, including mobile browsers, and also supports Node.js command-line use. Supported patch formats include IPS, UPS, APS, BPS, RUP, PPF, EBP, BSDiff, Paper Mario Star Rod, and VCDiff. Before patching, the tool displays CRC32, MD5, and SHA-1 checksums for the ROM. It can automatically unzip files and remove ROM headers. Developers can customise and embed it in a website as an online patcher for that site’s patches. The project lists Romhacking.net, Smash Remix, Radical Red, and other sites as users. The product page identifies version 3.3.1 and requests optional donations toward infrastructure costs. The product page gives no security certification or compliance standard.
