Super C Annotated Disassembly

About

Super Contra, released in arcades in 1988 by Konami as Super C in North America, is the sequel to Contra in which soldiers Bill Rizer and Lance Bean fight to stop another invasion by the alien Red Falcon. This is an annotated disassembly of the US NES version of Super C that reassembles with the included build scripts into a byte-for-byte match of the original ROM. The same source can also build Probotector II: Return of the Evil Forces, the PAL release of the same game, and the repo includes supplemental documentation covering the game's memory banks, known bugs, enemies, graphics, and sound engine.

Getting started

Building requires supplying your own Super C (US) ROM, which the build scripts use to extract the game's original graphics and audio; running the appropriate script for your OS (PowerShell, batch, or bash) produces a playable ROM, along with debugging symbol files that emulators like Mesen can load automatically.

Additional notes

Variant

The same codebase can also assemble Probotector II: Return of the Evil Forces, the graphically altered PAL release of the same game.
