That activity is the one I do in my spare time... See the thread
(sorry, it appears it is in French) for Moon Patrol:
http://www.hackzapple.com/phpBB2/viewtopic.php?t=13

Moon Patrol uses 4*4 coded nibbles, a single sector of $800 bytes per
track. It is easy to get the program back on disk, more difficult to
keep the moon base as it is loaded at every game. Moon Patrol requires
a complete rewrite of the load routines, if you are familiar with the
$C08x,x routines, then go for it ;-)

The program does not check two tracks occasionnally, it just loads the
moon base image.
