The tool people mean by the search is usually the browser engine on the home page. Everything else is a desktop program for one format, or an older hosted copy of a similar idea. I put them in one table so you can sort by what you already downloaded. A BPS from Floating IPS, a UPS from NUPS, an IPS from Lunar IPS, and an xdelta from Delta Patcher are not interchangeable menus. They are different authors writing files this site can often still apply.
Where a project publishes two version numbers I keep both. Floating IPS is v1.31 on the old utility listing and v198 on its releases. Rom Patcher JS is v3.2.1 as a GitHub tag dated 4 Nov 2025, while the page on marcrobledo.com was labeled v3.5 when the research was checked. This site pins commit 4f17297 from 21 Oct 2026 because that commit adds LZMA secondary decoding. I do not collapse those into one version string.
Hack64's version cell is empty on purpose. I did not find a numbered release to cite. ROMhacking.net's online patcher is the archived v2.8.1 copy. The live site turned into a news page in 2024 and the database moved to the Internet Archive. MultiPatch, UniPatcher, patchmyrom, and rompatcher.app stay in the table without detail pages. Use their project links for the current release and instructions.
The filter box narrows the rows, and a click on a heading sorts that column. Three questions still pick the row: browser or installer, which extensions it can write, and whether the license is one you can read. Then open the detail page if the name is linked in the guides below the table.
