Floating IPS (Flips) vs UniPatcher

Floating IPS (Flips) patches IPS and BPS files. It provides Windows and GTK+ graphical interfaces, command-line support, and a command-line-only build, and is listed for Linux, macOS, and Windows. The GUI can apply multiple patches to the same ROM and create multiple resulting ROMs. For BPS patches, it can remember earlier ROM choices and reuse one when it determines that it matches. The GUI can also launch another program after patching, allowing an emulator to start after a BPS file is patched. The project says Flips creates very small IPS patches and the smallest BPS patches of any known tool, and that it is faster than comparable creators. It is free and licensed under GNU General Public License version 3.0 or higher. The project is in maintenance mode: bug reports and pull requests will be read, but feature requests are unlikely to be implemented. GitHub marks the repository archived and read-only since May 21, 2025. Releases are automated for each commit, with an erratic schedule that can include identical releases.

UniPatcher is a free Android app for applying patches to ROMs from older console games, rather than native Android games. Users select a ROM, choose a patch, specify an output file, and start the operation with the round button through the Files app or another file manager. Supported formats include IPS, IPS32, UPS, BPS, APS for GBA and N64, PPF, DPS, EBP, and XDelta3. The app can create XDelta patches, repair checksums in SMD or Genesis ROMs, and remove SMC headers from SNES ROMs. Compressed games and patches in ZIP, RAR, or 7z format must be unzipped first. The project is licensed under GPL version 3. Its privacy policy says the app does not collect or transmit personally identifiable or location data and does not share personal information with advertisers, vendors, or analytics providers. Google Play reports no data collected or shared with third parties. Boris Timofeev is listed as developer.
