Spec score 6.4 #17 of 20 in ROM Patching Software

What it is

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.
