Well today is the time to tell the story: Back when Ralph Baer (who was working for Sanders Associates) sold the rights of the Brown Box to Magnavox. By 1971, Magnavox had made a few prototypes which they called "Skill-O-Vision" to market tests and ask people what did they think of the Skill-O-Vision, but during that year, Magnavox contacted a toy company to make the rifle guns (they surely contacted a few companies but one was chosen) and that company was Nintendo. Since e-mails and internet didn't existed in 1971, Magnavox must have seen Nintendo at a Toy Fair (i'm guessing...) or a person at Magnavox made research to find a suitable toy company. In any case, Magnavox stumbled upon Nintendo and asked them if they could do the rifle guns for them and they did. Nintendo already had guns and rifle guns which were called "光線銃SP 光線銃 カスタム" (aka Kôsenjû Guns) (click here to read about all the Kôsenjû Guns).
If you have checked the page on the "Before Mario" blog, check especially the "Kôsenjû SP Rifle" and see how this gun is the copy of the Odyssey Rifle Gun minus the small telescope sight. Still don't beleive it ? Then check these pictures of the Odyssey Rifle Gun and the Interton Video 3000 (from my collection):
Notice the battery compartments on both Interton and Magnavox rifles ? Yep, those battery compartments aren't used in those two rifles since they are powered by the console when pluged-in, but it is used for the Nintendo Kôsenjû SP since there is no cord attached. And now, check these pictures of the Nintendo Kôsenjû SP (these were taken on an Japanese auction site):
David Winter stated in an old message (still trying to find it) that the Nintendo Odyssey is almost the same as the US Odyssey. The only difference is the manual and the papers were in Japanese but the rest (overlays, cards, boards, etc..) were still in English. The only proof of the Nintendo Odyssey (for now) is a flyer that Toby Wickwire (aka Y-Bot) has a copy of the Japanese Odyssey flyer. Here's the pictures:
Sorry about the quality but these are the only size that exists on the Web, well until someone (maybe me? *grin*) ask Toby for better quality pictures or even better...scans! So this is the story on how Magnavox and Nintendo teamed-up 44 years ago.
