what if the api basically does this
Videos
downloads video,
converts video to .mp4 or .avi,
places video in folder displayed on screen with tumbnail, video info, comments, and more like tite, and video link.
thumbnails
downloads thumbnail,
converts to format For Wii,
puts in folder with other stuff.
What if theirs no space?
save video to watch history/YouTube account watch history with link to download to again and delete the old video file.
google accounts/YouTube accounts,
1 : trick the web browser id into some version of YouTube tv or for a version of android like 7.0 or 8.0.
2 : act like a older version of windows or chrome/firefox like windows x or windows x etc with chromium version xx.x.x you get the idea.
3 : we could maybe find a way it connects to a device like a older phone, tablet, computer, or more to log in, that's what the Wii U used and some smart tv's use.
api
this is what I'm thinking, we could edit. it a only work a little so it can somehow connect to a third party sever that packs up the files for the Wii and displays the thumbnails and titles with the youtube channel that created it, with the time and it acts as a ghost with the api .sfw and link on a server and when you click on the video it buffers for a minute 2-3 minutes and then plays, or downloads half of the video then later downloads the other half. It's not practical but who is using their Wii to watch YouTube full time? Probably not a lot of people.
Conclusion
there's many Many reasons why this won't work at all maybe a little the most unlikely to work is the api and videos with it info. I know there is still a slight chance it might work but I don't think it would the reasons are obvious yet a little hard to spot. The only reason I want this to get fixed is so I don't half to sit in a uncomfy chair to watch YouTube at my desk on my computer and give my Roku a break it's on like ALL TIMES!!! So it gets so hot, so I want to give it a break and sit back relax and see what the hell I can laugh at YouTube recomending me today and laugh at stupid dick jokes I see that are kinda funny,
