# Super Mario Bros.: ca65 reconstruction of seven releases

> Super Mario Bros. Disassembly reconstructs seven NES, Vs. System, and Famicom Disk System releases as readable ca65 modules. Its build splits assets from user supplied images, rebuilds each supported revision, and compares the result byte for byte with the original; documentation maps source modules and game data formats.
