NUPS review
A free Windows desktop utility focused on creating and applying UPS patches.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NUPS is a free desktop utility for creating and applying UPS binary patches, including patches for game ROM files. It is aimed at people who need to apply a UPS patch to a file or produce one from an original and a modified file. The tool is associated with its creator, Nintenlord, and its documented role is patching rather than broader ROM editing.
Its scope is straightforward: choose a file to patch, or compare an original file with a modified version to create a UPS patch. NUPS also displays details about a patch, which can help users inspect the patch itself. The supported patch format is UPS, so this is a focused choice for workflows that already use that format, not a general-purpose multi-format patch manager. Its stated use covers multiple games rather than a single game-specific editing environment.
NUPS is distributed as a standalone Windows desktop utility, with a free plan. It is a better fit for solo users seeking a dedicated UPS patching tool than for those who need a wider ROM-editing workspace: it does not offer tile or sprite editing or a hex editor. Choose it when creating or applying UPS patches is the main task; consider a broader editor if graphics or direct hexadecimal changes are central to the work.
