Hey Itizso, I managed to find some EBay listings that might be of use to you - are any of these helpful with getting you the info you need?
Finding video has proven to be very tricky, although one of these listings does have a few seconds of a very clear video - I hope this helps in some way!

Sure - I originally found it on this old auction page here:
Do you think you'll be able to find the graphics somewhere? I'd hate for this not to get made after finding all of the documentation, as it's likely the only way that I and anyone else interested will ever be able to play these games (these watches sell for several hundred dollars on EBay, which is kind of a lot for what it actually is.)
I hope that you'll be able to make these with all of the information I've given you so far, and that you'll be able to find the rest either online or with the help of someone else here in the community.

I also managed to find this image of the Luigi instructions in English, so there's now a complete set in English for three watches here. Would it be possible to take screenshots of the Youtube videos and then zoom in on them? I also wonder if the manuals might help with the graphics? Hoping you'll be able to make these soon.
I also found an old Ebay listing for the Mario watch as well, which has a listing of the American manual pages

Not a problem - I created a post with a G Drive link that has all the information in it here:
https://itch.io/t/4900799/nelsonic-mario-watches-manual-scans-and-additional-gam...
Please let me know if this is at all helpful, as I'm hoping all of this info put together is enough to help you create these simulations!
Hello - I'm hoping that you'll soon be able to add the three Nelsonic watches from the Mario collection to this collection. I've put together a RAR here that contains the following information:
- PNG scans of the manuals for each watch (in Japanese, but that's all I could find at the moment)
- AI translated versions of the manuals in easy-to-open Word docs
- Links to the websites where I found the information on each watch in a seperate text file - the websites do a fantastic job at explaning the rules of each game and how they're meant to be played, which will hopefully supplement the imperfect AI translations that I was able to provide
All of the information is avaialble in a RAR here:

Please let me know when you download it so that I can set the folder back to Private again!
Best,

Hi Itizso - the work you're doing here is absolutely amazing! I have a question for you - is there any way that you could create a simulation of the three Nintendo watch games that Nintendo released as promotion items in the early 90's? Here are YT videos for each of them:
Mario's Egg Catch -
Princess Toadstool's Castle Run -
I tried to find the instructions for you, but wasn't able to come up with much of anything - I hope that you'll be able to make recreations of these soon, as they're incredibly hard to find and would make a great addition to your collection here.
Thank you for all of the hard work you've done on this project so far - hope to hear back from you soon!
