ThirdTube VS Universal-Updater

It actually doesn't! This is a homebrew client called ThirdTube giving you glorious 144p YouTube on your beloved Nintendo 3DS!

If you have a Github account and go to the Thirdtube page, you can actually download experimental builds from the "Actions" tab that work on O3DSes!

yeah, it's called thirdtube

If you want up to 40 Nintendo DS game icons "installed" on your 3DS Home Menu, you need to use another homebrew app called NDS Forwarder Generator. You can find and download it from the Universal Updater homebrew app.

There is a free way to install homebrew on any 3DS/2DS; Universal-Updater. Been around for a while, actually.

Here's the link to the download page of UU, including QR code.

I can't speak to why Universal-Updater doesn't show the latest version of Luma3DS available for download and installation, but you can update Luma3DS to the latest version yourself manually quite easily as explained in my first reply. Have no worries, you didn't mess anything up.

Basically, you'll want to download the .Cia and .3dsx files for FBI from the FBI GitHub. Open a default installed app that you never use (the AR one for me). Then press L+Dpad down+select to open the Rosalina menu. In the Rosalina menu select "Miscellaneous options" then "Switch the hb. title to the current app". Next close the Rosalina menu, close and reopen the app. It will open as the homebrew launcher. At this point you can open the FBI.3dsx from the homebrew launcher and use it to install the FBI.cia. You'll be up and running and be able to install whatever you need at this point. I recommend the Universal-Updater to open up your options.

Assuming the 3DS is already modded you can install Universal Updater (Homebrew appstore) and download it. It puts all the files where they need to be.

Was anemone ever on your homescreen? If it's installed it should be listed in "Titles" on the main menu of FBI. If you can't find it anywhere you can download it from universal dB on your 3ds, if you don't have universal dB either go here and you can either remote install it by scanning the qr code through FBI, or you can download the .cia file put it in your cia folder of your SD then install it from there through FBI

The easiest way to get TM++ is using Universal-Updater. Universal-Updater is available as either cia or 3dsx. The cia will install to your home menu using FBI. The 3dsx version you just copy to /3ds on your SD card, don't need to install, and run through Homebrew Launcher. You only need one or the other, and you should choose based on whether you prefer a direct home menu icon or a tidy home menu. Twilight Menu++ is only available as a cia, but the reason I suggest using Universal-Updater to get it is because it has a bunch of other files it needs that you'd have to copy to the right locations if you install it manually. Forwarders are always cias you install through FBI.
