Thanks the help. I'm trying all this out now. This should let me enjoy the game until I get the version for the Switch.
EDIT: Is there perhaps a torrent link for these multi part files from the video? It'll download much quicker that way.

I just edited the last post, btw. I see someone in the comments was talking about a magnet torrent file link or something, but I can't understand the language.
It's in Portuguese. Now I have to translate the comments to understand information about a translation patch.
Oh man!
The video description of the video actually have english description option but the comments are in other language, someone other than the video uploader made a torrent and shared the magnet link in the comments but it seen the link or torrent is broken (maybe that's why don't have it on video description).
I know it's a pain for some to get hardware like HDD but its way cheaper than SD cards and have much more space to install Wii U games so i recommend you try to find a HDD to use on your wii u instead of trying to convert the game because its not so easy to decrypt/unpack/encrypt/build wii u games and (
for noobs like me xD) these fail most of the time after much time wasted. 
And the pack provided is already patched and is fully functional.
I find much more convenient to use this way.
btw here's a tip: if you like the original Japanese Voice Acting like i do you should try to get the Steam version of Puyopuyo Tetris instead as it have option to use english texts and Japanese voices. (the localized Switch version have only english voice acting). (correct me if there's a update and i'm wrong xD)
ignore it).
