Zeta Series

The Zeta titles are a series of diskmags released between 1986-1987. They apparently came with a magazine.

This is 1 of 3 diskmag series released by Champion Soft with the others being Omega and Lemonade.

The idea of Zeta was to make a "Graphic Idol" group, sort of virtual idols if you will. Some of them even got spin-off games like Miki

These titles include various minigames or CG viewers. Most of them are quite small as it's supposedly an extra to the magazine.

All of the titles ask if you have 1 or 2 drives before loading on.

The final option always ends the game with a slight change in graphics/message and some music.

Zeta #1
The secret code can be found if you check the pattern above the fishbowl. This hint is found if you perfect the Swimwear Course. It's 23, type this in on the menu.

Miss Zeta Contest
Introduces the 6 candidates with a bio and CG shot for each.

Zeta Quiz
You are presented with two images, however they are slightly different. Your goal is to find the differences and you get 30 seconds to do so. I assume this was used for a contest as there's no gameplay element to it and there's a heap of instruction text before it.


 * Her right eye is closed
 * Her shoulder strap is untied
 * The plant has one more leaf
 * The boombox has a few more holes in the handle
 * The light blue book has a different title
 * No title on the second book from the left

Swimwear Course
Move the heart cursor over her body and find the sweet spot. You need to find 7 within 10 tries. Clear it and get CGs. Clear it without mistakes and it'll tell you about the secret on the menu screen.

Close Coverage
This section requires a code found on page 25 of Zeta magazine. It hasn't been found as of yet.

Zeta #2
This one has 2 secret codes. 44 tells you that you've typed in the devil's number and you're stuck until you rest accompanied by loud beeping noises. 336 loads a CG and song related to the Hanshin Tigers. This code speeds by if you end the game.

Miss Zeta Announcement
Result announcement of the first issue's contest.

That girl's scandal
A CG viewer. It covers an event with one of the girls.

Bad summer vacation
A sugoroku style boardgame. Your goal is to reach 800 points by the 31st. It's controlled by rolling the dice and moving that amount of days. Every day has an event tied to it. There's 2 CGs to be found on the board itself on day 14 and day 21.

Atwiki has a full list of events here.

Zeta Quiz
You are presented with two images, however they are slightly different. Your goal is to find the differences and you get 30 seconds to do so. I assume this was used for a contest as there's no gameplay element to it and there's a heap of instruction text before it.

Zeta #3
The secret code is 128 for this title.

Zeta Gal 10 Big News
A collection of CGs based on the 10 biggest news items of the ZETA gals in 1986.

Gym Clothes Course
It's black jack. Get closest to 21 to win, don't go over. 10, J, Q, K are all 10. A is 1 or 11 depending on the total value of cards, over 21 makes it 1. Get 100 coins and get a CG. You start with 2 coins, but if you clear the 2 Jigsaw puzzles in "The Jigsaw Puzzle" you can start with 20.

That girl's scandal
A CG viewer. It covers an event with one of the girls.

The Jigsaw Puzzle
A jigsaw puzzle minigame that's found in quite a few other titles. You can check 3 times before you game over.

Yakyūken
Win in 4 Yakyūken (rock-paper-scissors) battles. Maiko-chan will lose some clothes and it'll tell you a hidden code.

Zeta Quiz
You are presented with two images, however they are slightly different. Your goal is to find the differences and you get 30 seconds to do so. I assume this was used for a contest as there's no gameplay element to it and there's a heap of instruction text before it. Sadly the copy I have has some corruption issues on some CGs. This is 1 such case, can't tell the differences.

Close Coverage
It's a sort of typing game. A letter appears in the purple frame and you need to type it. You have to hold shift to type in caps. The time becomes shorter as you progress, there are 6 CGs.

Zeta #4
The secret in this game is 517.

ZETA GAL School uniform
A CG collection that shows the ZETA gals in their uniforms and their plans for the future.

Pajama Course
You pick one of three girls and take them on in a panel flipping game. Win and you get a CG. Panties are worth 1 point, if you pull pants? your points are confiscated and if you get a bra all confiscated point are awarded to you. The layout is random. You move using 2468 and enter to uncover a panel.

The Search For Mistakes
You are presented with two images, however they are slightly different. Your goal is to find the differences and you get 30 seconds to do so. According to Atwiki, the contetst had a deadline of June 1987 and you participated by sending your answers on a postcard. 10 people would be drawn by lottery. The prize was a Cel of a ZETA GAL.


 * Her hair ribbon is a different colour
 * The icon on her sock is different
 * One of the flowers on the top right ball is green.
 * She has one less shoelace.
 * One of the faces in the lower left is blue.
 * The light blue/bue pattern around her butt has an different icon.
 * There's a tree with coconuts below the white ball in the lower left.

Jigsaw Puzzle
A jigsaw puzzle minigame that's found in quite a few other titles. You can check 3 times before you game over. Win and you get a hint to the secret for this issue.

Close Coverage
A game of Simon. There are 6 coloured panels. Combinations are random? First you need to do 4, it increases to 6 and 8 and the speed increases too. After doing the 8, it asks you for a number which can be found by solving the quiz on page 45 of the magazine?

Date with Kyouko-chan
At first you get a blackjack type game. The large (1) or small (2) indicates if the hand goes above or below 40. It's luck based with some slight planning. Your 2nd digit should be close to 9 and you should've picked if it's larger or smaller? My wins stopped going up, but I did get a CG. So I might've just gotten a last lucky win?

Minaho's Past, Present and Future
A CG collection of Minaho in various phases of schooling. Apparently the "time machine" breaks down at times, keep trying if you don't see a CG.

Zeta Gal's Summer Patterns
A CG collection with a summer theme.

ZETA GAL's Underwear Encyclopedia
It's a sort of roulette which decides the bottom half of her underwear, having the same colour 3 times in a row is a game over. So hopefully you get it to alternate, your goal is to get plenty of the same colour as her bra. 9 for the last stage? There are some special messages by getting a certain combination on certain days, apparently. You can get hints for the sea pick-up game if you win.

Zeta Quiz 100
A multiple choice (4) quiz that randomly selects from 100 questions. There are 4 categories which are also randomly picked: Fashion, Food, Body and other. You get 9-20 questions and answering correctly raises the Gondola a bit. Answering 10 correctly in a row or reaching the 10th (for 9 questions) is a win. Your reward is a message from Yukiko and a CG. There are various different comments for the CG apparently. The game can randomly end itself, though it didn't happen to me.

Picking up girls at the sea
an ADV game, uses a command menu instead of the previous text parsers. There's currently no solution out there, so here's a link to what Atwiki figured out.

Find The Cat Quiz
Your goal is to find as much cat shapes (eyes and ears) in one image. Works the same as the difference images. You were supposed to note it down on a postcard and send it in for a prize. There's quite a few, but they are quite easy to find so it's easier to find them by looking than to list them.

Zeta Gal Cockroach Hunter
A game where you place traps on a 10*29 grid. You get 20 traps and there's around 30 roaches. Your goals is to kill 5 of them. It's possible for roaches to spawn in the same spot, regardless of there already being a roach. Completing it gives you a hint for something, probably the sea pick up game?
