ROM Bin Patcher (rombp) vs UniPatcher

ROM Bin Patcher (rombp) is a free utility for applying IPS and BPS patch files to ROMs, a process commonly used for retro gaming modifications. The maker built it primarily for the RG350M handheld running OpenDingux, and it also runs on desktop Linux. The maker reports testing on the RG350M and Ubuntu 20.04; other OpenDingux MIPS64 handhelds may work, but testing is reported only for the RG350M. To install on OpenDingux, the instructions point users to the latest OPK on the GitHub releases page. When patching, rombp first makes a copy of the source ROM, leaving the original file intact. It saves the patched ROM in the patch file’s directory, using the patch file’s name. Command-line options specify the input ROM, patch type, and output file; starting without options opens the SDL interface. The RG350 build links against uclibc and SDL2. The repository includes an MIT license that permits use and modification subject to its terms and disclaims warranties and liability.

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. Bug reports use GitHub Issues, while questions and feature suggestions use GitHub Discussions; translation contributions go through Weblate.
