Spec score 7.5 #10 of 20 in ROM Patching Software

What it is

flips.rs is a free, open-source Rust bindings library for Flips, the Floating IPS patcher. It applies UPS, IPS, and BPS patches, creates IPS and BPS patches, studies IPS patches, and reads BPS metadata. Although the README discusses video game cartridge ROM patching, the API can apply patches to arbitrary sources. The project says Flips creates small BPS and IPS files among widely used patchers. The crate supports no_std when its default std feature is disabled. It uses crc32fast instead of Flips’ naive CRC32 algorithm for BPS and UPS patch creation and application. Checksum verification is supported. Version 0.2.1 is listed, with flips-sys 0.2.1 as a dependency, and Martin Larralde as author. The library is licensed under GNU GPL version 3.0. Distribution links point to crates.io and docs.rs. The listed platform is Linux, and the plan is free.
