During what I'll call
the experimental
years of the mid- to late 1980s, when Nintendo Co.,
Ltd. released the Disk System and was pushing it
into the Japanese gaming market, along came
companies seeking to profit from the conveniences of
the new system. The Disk System didn't have any
advanced lockout features and the disks were easy to
manufacture and write.
Nintendo licensed games for use with the Disk
System, but as might be expected, wasn't willing to
license games with explicit sexual content. A number
of unlicensed porn games were released for the Disk
System, from such companies as Hacker International,
Mimi Pro, Phoenix, and Super Pig.

Hacker International
is best know for its cartridge games, three of which
were published by Panesian for the NES, but
also for Alien Battle, considered the
nastiest Disk System porn game -- with graphic
intergalactic sex scenes, it far surpasses the
indecency of any other porn game. Hacker
International released at least six games for the Disk
System, one of which was co-released with Super Pig.

Fairy Pinball is a Hacker International
title.
Mimi did well for
itself, releasing two series of porn games totaling
11 games, but its games remain unpopular and largely unknown
to English-speaking gamers. Mimi's released tended
to center around popular Japanese games like
Mahjong. Phoenix is unknown to
most gamers, too, because it didn't release but a couple
unlicensed titles.

Though one might
suspect the porn king, Pony Canyon, might've
released porn games to go along with its VHS porn
empire, it didn't. Pony Canyon, the publisher of
clean cartridge titles like the Dungeons & Dragons
series and Lunar Ball, is known to have taken time
from its video games to release X-rated films, such
as the series below.

There's also the mysterious Sezon,
which played some role in developing or publishing
unlicensed games and is often on game lists as
having released at least two games. Not much is
known about them, and I have yet to see any of
Sezon's games for sale anywhere.
So, having introduced
you to the rest of the porn game publishers, we're left with
the "computer magic" of Super Pig, a company that
produced porn games that go as largely
unrecognized as those by Mimi and Phoenix.
Super Pig
wasn't a company of creative genius, but
was active in the 1980s producing
spin-offs of popular games. For instance, Sexy Invaders
is a spin-off of
Galaxian. My favorite Super Pig game, because of
the wordplay in the title, is Sexy Slot and
is more akin to Hacker International's AV
Pachi Slot than anything else.

Super Pig only
released disks, and instead of boxes or the standard
clear plastic disk case, they come in what look like
mini music record sleeves. Instead of the disk
sliding into the sleeve like a record would, the
sleeve opens like a book and the disk is secured by
a cut in the sleeve. Most of the unlicensed porn
titles come in unique cases, usually something
similar to today's DVD cases. Super Pig used those
types of cases as well.
Often in the gaming
community, Super Pig isn't given credit for its own
games, when gamers and collectors confuse Super
Pig's quality games with Hacker
International's games. That's hogwash. Give the pig
the recognition it deserves.
