That patch applies to RocknRoll (c) 1989 Rainbow Arts, rerelease version.

Fixed:  Stackframe error.
        Several dbf-delays replaced.
        Crash after completion of the game (hopefully) fixed (Not tested 
         already, completing the game with the shortest way takes at
         least 2.5 h and 2 times testplaying is enough to me).

Quit game with F5.

Notes:  Try COUNTRY or MAGIC MAP instead of your name, or the levelchoice
        with RAINBOW ARTS . Magic number for levelchoice is aaxxbbbbxxcc.
        Hereby is aa the level you want and cc the level backwards, and
        sum of bbbb gives the levelnumber. Example: 25XX6667XX52.
        Do not edit the highscorefile, or the game wont work anymore.

Additional note: There is one defective charge of that rerelease. I managed
        to restore the defective data and included it (encrypted) in the
        imager. If you have that charge too (it crashes in level 7 or 8) you
        need to install your very original disk and not a backup, or the
        defective track (#5) cant be recognized and will not be restored.
