Patcher64+ Tool vs rom-weaver

Patcher64+ Tool patches ROM files and Wii Virtual Console WAD titles using included or custom patches. Native mode handles ROM files, while Wii VC mode works with WADs. The tool currently supports Nintendo 64, NES, and SNES consoles and accepts BPS, IPS, Xdelta, VCDiff, and PPF3 patch files. In Wii VC mode, users can insert a custom ROM into a WAD, apply selected modifications, or extract its ROM. Supported games may offer Redux enhancements and settings for audiovisual details, difficulty, color, equipment, cutscenes, and language. The patched file is saved beside the original, which remains unchanged. The listed requirements are 64-bit Windows 7 or newer and PowerShell 5.1 or newer; the repository also provides Linux and Mac installation guidance. The project is free and licensed under GPL-3.0. The README notes that Majora's Mask, Super Smash Bros., and Paper Mario need their respective modes rather than Free Mode for patching. Support is available through Discord, and bug reports should include the console log and reproduction steps.

rom-weaver is a free, open-source tool for patching and converting ROMs and disc images, and for assembling patch steps into reusable bundles. Its browser and command-line editions share an engine. Users can apply patches, create patches from ROMs, and arrange ordered workflows. The support matrix includes formats such as IPS, IPS32, BPS, UPS, xdelta, and PPF, with some format-specific limits. The tool can inspect and extract many archive and compressed image formats, including ZIP, 7z, RAR, CHD, RVZ, and Z3DS; creation support depends on the format. It can bake supported cheat codes into ROMs or save selected database cheats as patch files, but runtime-memory cheats are unsupported. Save editing covers specified Pokémon save layouts and The Legend of Zelda: A Link to the Past SRAM, subject to game recognition limits. The browser uses WebAssembly to process files on the device; the CLI reads and writes local paths. The maker says files and results are not uploaded. The browser app can work offline after caching. It is available for web, self-hosting, Linux, macOS, and Windows, and requires no account.
