Did you know?

This is a rare original Nintendo OEM (Original Equipment Manufacturer).  As Nintendo didn't have their own distribution centres in various countries, Nintendo sent the game in this box to the different companies to distribute the game in their country. The company (for example Ji21 and tricOtronic) would then package the game in their own designed box and sell it.



Have you ever wondered why Mickey Mouse has the label DC-95 and Donkey Kong Circus has the label MK-96. Me too and I believe that Nintendo got it the wrong way round. If anyone knows more about this then let me know.



The game that features most in the Game & Watch series is Super Mario Bros. There is YM-105, YM-801 and YM-901. All the same game in different formats. You might say there are 3 'Popeye' and 3 'Donkey Kong Jr.' also, but Donkey Kong Jr. DJ-101 is not the same game as CJ-71 or CJ-93. Popeye PP-23 is not the same game as PG-74 or PG-92.

'Fire', 'Manhole', 'Snoopy', 'Mario's Cement Factory', 'Climber' and 'Balloon Fight' are the same game and come in 2 different formats.



Did you notice that Nintendo's first released Game & Watch Ball (AC-01) and Nintendo's last released Game & Watch Mario the Juggler (MB-108) are more or less the same game. I think it was intentional as they wanted to end the Game & Watch series as they Started. A kind of loop.



As you know Mickey Mouse (MC-25) and Egg (EG-26) are exactly the same game with different characters. Egg is far more rare as it was released in certain countries only. If anyone knows more about this, then please let me know.


Over 1,600,000 Game & Watches were sold from 1982-1983


All games have a 'test' mode. Most of them light up all the crystals when you put in the batteries or press the ACL button. Those that don't you will have to hold down the Jump/Eject button while you put in the batteries. The test mode will be there until you release the Jump/Eject button.

Here is some useless information. If you don't want to press the ACL button you can press the following buttons simultaneously to get the same result:

Turtle bridge (TL-28): Time + left button + right button
Fire Attack (ID-29): Time + lower left button + lower right button
Snoopy Tennis (SP-30): Time + left button + lower right button
Oil panic (OP-51): Time + both buttons
Mickey and Donald (DM-53): Time + down on left button + right on right button
Greenhouse (GH-54): Time + down-right
Lifeboat (TC-58):
you can activate game 'B' by holding in the Left and Right button, and then pressing the Time button.
Squish (MG-61): Time + down on left button + left on right button
Donkey Kong Jr. Panorama (CJ-93): Time + down-right
Manhole (NH-103): Time + lower left + lower right


More interesting trivia:

Balloon Fight: you can get to the 17th level by holding the time button as you press the game button.

If you hold the Jump button and then press the Game button In Super Mario Bros YM-105 you will start at level 3-1.

The game where you are allowed the most misses is Mickey Mouse (or Egg). You can get up to 6 misses (only if you miss when Minnie (or the Lady) appears) before the game ends.
Oil panic you can miss 5 times before the game ends.

Bomb sweeper is the only game which has only one control-panel. The game with the most buttons (10) is Donkey Kong Jr. (Separate buttons for Up, Down, Right, Left, Jump, Game A, Game B, Time, Alarm and ACL).



How did Gunpei (Nintendo's Game & Watch creator) manage to make the Tabletop and Panorama games in colour, since a LCD screen can only have two states, either see through or black. The clever thing here was that he reversed the technique he had used on previous Game & Watches. Instead of the figures, characters and hazards showing up as 'black' (on) he made them see through (off). This means the background is in colour and when nothing is there the crystals are 'black' and when you move your character around the crystals where he is at become see through. Get it? The only problem with this is that you need a light source behind the colour masks to be able to see the characters.


The most popular game ever was Donkey Kong and was introduced in 1982 as one of the 'Multiscreen' series.

The interesting thing about the 'Multiscreen series' is that because Nintendo patented the game housing (unlike the other versions) there were hardly any pirated copies. Many companies stole Nintendo's concept in the early days and produced their own bootlegs of Nintendo games. The most obvious are the Russian games.

Licensing of game characters continued. In the game Mickey & Donald (DM-53), three popular Disney characters appeared. Mickey Mouse, Donald Duck and Goofy. Then there was Snoopy, Popeye and Nintendo's own Donkey Kong, Donkey Kong Jr., Mario, Luigi and Zelda



The serial number system that Nintendo used was based on a 2 plus 6 digit scheme. The two first numbers was pre-stamped on the label, the six remaining digits was a sequential number.


There were exactly 60 different Model Nr. of Game & Watches made. They are: AC-01, FL-02, MT-03, RC-04, IP-05, MH-06, CN-07, LN-08, PR-21, OC-22, PP-23, FP-24, MC-25, EG-26, FR-27, TL-28, ID-29, SP-30, OP-51, DK-52, DM-53, GH-54, JR-55, MW-56, LP-57, TC-58, PB-59, BJ-60, MG-61, BD-62, JB-63, MV-64, ZL-65, CJ-71, CM-72, SM-73, PG-74, SM-91, PG-92, CJ-93, TB-94, DC-95, MK-96, DJ-101, ML-102, NH-103, TF-104, YM-105, DR-106, BF-107, MB-108, BU-201, UD-202, BX-301, AK-302, HK-303, YM-801, DR-802, BF-803 & YM-901.

There could have been 61 had Nintendo decided to release Tetris (TR-66). Unfortunately Nintendo thought it might ruin sales of the Game Boy version. There are rumours that some got out to the public, but that is just rumours. I have yet to see any, but if anyone has any they would be worth a fortune.  You can however buy the mini classic version if you want to see what it would have looked like.

Originally OEM was an adjective used to describe a company that produced hardware to be marketed under another company's brand. Mitsumi, for example, produced CD-ROM drives that dozens of companies would label as their own. It's often now used as a verb, as in this sentence: "This CD-ROM drive is OEM'd by Mitsumi."
