Pro tip for technology people: You know those online newspaper articles that won't let you read them unless you have a subscription? Some of these you can bypass by using private mode or deleting cookies, but sometimes that doesn't work either...
So, of course, then you just have to put "view-source:" in front of the URL and then you can read it just fine.
Dang, I just tried using the Japanese Nintendo website to download Famicom Online, but it didn't work - it showed the account icon for my NoA account in the corner, but once I hit the download button it logged me out of the Japanese website. I was really hoping that would work.
There's a Nintendo website that allows you to sample Joy-Con colors here.
Well, I was fiddling around with it and noticed that what colors are displayed is determined in the URL, so I messed around a little bit and learned that you can use this to make colors appear that don't exist for that side (for example, making the right Joy-Con neon purple, when the color is actually exclusive to left cotrollers). This works with the wrist straps, too. (This is an example of impossible colors.)
