Extent of Modification

The visualization on this page offers information about the extent of modification that a given mod patch file instructs the computer to execute with respect to the original Super Mario Bros. ROM. In other words, this interactive visualization, which can be sorted and filtered by modder, mod, or even by a range of particular byte addresses, provides basic numerical information about the amount of change contained in a mod or set of mods. This can be useful for purposes of comparison and for identifying and narrowing down possible correlations and connections between modders or their mods.
