flips.rs
What it is
flips.rs is a free, open-source Rust library providing bindings to Flips, the Floating IPS patcher. It applies UPS, IPS, and BPS patches, creates IPS and BPS patches, examines IPS patches, and reads BPS metadata. Although its README discusses video game cartridge ROM patching, the API can apply patches to arbitrary sources. The project says Flips is known for producing 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 to improve BPS and UPS patch creation and application performance. Version 0.2.1 lists flips-sys 0.2.1 as a dependency and credits Martin Larralde. The library is GPLv3, distributed through crates.io, and documented on docs.rs. Checksum verification is supported, and Linux is the listed platform.
For and against
For
- Applies UPS, IPS, and BPS patches
- Creates IPS and BPS patches
- Supports no_std Rust builds
- Uses crc32fast for patch operations
- Provides checksum verification
Against
- Listed platform is Linux
- Licensed under GNU GPL version 3.0
- No free trial is offered
The verdict
flips.rs offers broad patch-format operations through a free Rust binding library. Its no_std option, checksum verification, and documented distribution channels may fit developers building patch tooling.
Who it suits
It suits Rust developers who need patch creation, application, inspection, or metadata access, including ROM-related workflows. Its Linux listing and GPLv3 license matter when planning deployment.
