This game reminds me of one of those old
Spectrum games where you could just see the
shoddy worksmanship, because the game was
written half in BASIC and half in Z80
assembler, or it reused BASIC drawing routines
and you had to wait for the circles to be

On the Genesis, it's less obvious, but here are
some clues. The game has low FPS (it feels like
10 FPS). There are slow loading times, probably
due to the decompression they use, and the fact
that they store pointers in little endian on a
big endian machine). It takes about 3 seconds
just to open the pause screen. There is always
input delay. As an example, take the pinball
level and see how much it takes from when you
press A and the flippers activate.

The game is ported from another platform.
Wikipedia says it was initially released for
the Apple IIGS. It is unclear which version is
ported to the Genesis. There is a secret level,
called Knock-out Nightmare. I believe that in
this port, it is not secret anymore. If you try
to access it via putting in the mouse hole on
the Energy Enigma level, when the mouse eyes
are red, you get a "Nice try!" message. It
comes right after the Ambling Ant Hill level.
Also, there is a Magic Carpet level that is
missing in the Genesis version. See the
GiantBomb page for more details (links below).

The gameplay is not bad, and the music is
decent. The instruments are mediocre, and no
PCM samples are used to enhance the sound.
There are very few in-game sound effects.

There was no sound test, so to get to all the
songs, I had to use GameGenie cheats to skip
levels. The songs do not loop, but there is a
'Repeat' option in the menu. But that only
starts the song again, after a silence of a few

They seem to have made their own sound driver.
With help from Valley Bell, we figured out a
way to get the songs to play in the level
opening screen (write 0x01 at 0xFFE28C).
This helped rip the song for Chaotic Castle,
which has an alert sound playing intermittently
during the level (for when the castle gate
opens). Interestingly, if you write 0x00 at
0xFFE28C, the notes finish playing at their
designated time. We also found the music files
inside the ROM, in SMUS format. Info about the
SMUS format can be found here, for anyone
seeking more details:

It is probably possible to extract the SMUS
songs and convert them to MIDI. Some of the
songs are compressed. It's possibly something

Each song has an internal name. In the ROM, as
well as in RAM, their positions are stored in

The value list at 0x005CAA is really the size
of the decompressed songs. If the value is 0,
the song is uncompressed and read directly from
ROM. Else it's decompressed to FF80E8.
