BPS Super Mario Bros. 2 Patcher is a free browser tool for applying a BPS patch to a Super Mario Bros. 2 ROM. Its page has separate upload controls for the ROM and patch, plus an Apply patch button. The patcher checks both files and reports when an upload is not accepted. It supports the NTSC ROM version; an invalid ROM may be a bad dump or from another region. During validation, it checks and swaps iNES 1.0 and iNES 2.0 headers as needed. It also matches the ROM revision to the patch, recognizing ROM and patch checksums for revisions 0 and A and applying a revision conversion patch when appropriate. Once the patch is applied, the script saves a .nes file named using the patch filename. The project page links to source code on GitHub, which includes BPS handling code, ROM file and hash code, two revision patch files, and the page script and styles. The page credits Marc Robledo for Rom patcher JS; his maker profile describes him as a computer engineer. The tool runs on the web and does not offer batch patching or command-line support.
