Diff Compare Mods (Patched ROMs)

This page enables low-level analysis of mod files, accessed here through a browser-based hex editor. Two files (from the complete collection of patched ROMs, as well as the original unpatched ROM) can be selected for byte-level diff analysis. In comparison with the Tableau-based diff maps, which reveal only the location of modifications, this tool further enables identification of modified contents. As a tool for close reading of a pair of files, it is best used in conjunction with the broad distant reading of the other tools, in order to zero in on correlations and differences previously identified in a cursory manner. Beyond this, however, the tool can be used on its own to compare files with a known relation (e.g., different versions of the same mod or various mods by the same modder).
