Another year and another HD patch but still the same nice person who provided
the dumps from original disk and from Shooting Stars 2 compilation.
Thank a lot to him (and for typing the manual).
Both version have damaged tracks, but fortunately I managed to get a good dump
by mixing the good tracks (even with no data track checksum).
There is a bug on disk version that it tries to load a no existing level 25,
(the game has only 24 levels). The custom disk loader fails to decode the track
and the end sequence will never be displayed. Of course, this slave fixes it.

Here some asm code which have been encoded with the track:
