BPS Super Mario Bros. 2 Patcher vs Patcher64+ Tool

BPS Super Mario Bros. 2 Patcher is a free web page for applying a BPS patch to a Super Mario Bros. 2 ROM. It provides separate upload controls for an SMB2 ROM and a BPS patch, then an Apply patch button. The page validates both files and shows invalid-file messages when they are rejected. It supports only the NTSC version; the page says an invalid ROM may be a bad dump or the wrong region. During validation, the code checks iNES 1.0 and iNES 2.0 headers and can swap them as needed. It recognizes ROM and patch checksums for revisions 0 and A, and can apply a revision conversion patch. After patching, the script saves a .nes file named from the patch filename. The project links to GitHub source code containing BPS handling, ROM and hash code, revision patches, scripts and styles. The page credits Marc Robledo for Rom patcher JS.

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.
