<code>vmunix</code> is the name of the executable file that holds the bulk of the game code on most of the Atari/Midway HDD based games. Normally found in the <code>CODE</code> folder, Rush 2049 and its variants load this file into memory after the filesystem has been mounted, and execution jumps over to it starting with the the controls calibration screen. The normal test menu is also present in this file, while the boot ROM hosts the <code>QA DIAGS</code> menu that can be accessed even if the HDD is not present.

''' Using these patches assumes you know how to use a hex editor and how to extract <code>CODE/vmunix</code> from the HDD or how to find the file on the drive directly. Improper patching will result in glitches or game crashes, and linked machines with mismatched patches will result in race desyncing.'''
