Can't see the size 'cause all the roms are not inside a zip file.
Edit: A reply would be nice :)

These collections seem to be up to date; I'm finding every file I need. I wish I could keep them in *.rvz format but I am using the basic redump dats so I have to use *.iso stored in torrent zip (*.7z) files. These 3 collections are great. Dolphin converts *.rvz to *.iso in like 10 seconds a piece so don't worry about a hassle during conversion, there is none.

For Wii users, yoh might want to know there are a few setbacks. This plentiful list collection will run -almost- all games.
Pac-Man World 2 just crashes, I recomend the Europe version instead, but that one also crashes after a while.
Sonic Riders crashes after a few Story missions. The Europe version doesn't.
So far I've only found those errors, but the rest of the games I've tried have all worked fine for me using Nintendont.

I don't want to compromise the playability, the default settings were chosen by the dolphin dev team for good reasons, you can find more about it here: https://www.reddit.com/r/DolphinEmulator/comments/q02im1/so_what_settings_for_this_are_the_best_what_file/hf50m1z/

Archive.org scans the files with antivirus applications after the upload complete, if any malicious data it's found, the whole archive it's taken down, so far this archive remains online, that might answer your question.

I tried to upload a text file after deleting the torrent file, and for some odd reason didn't generate a new one, until this solution gets fixed, I recommend you to use a download manager like jdownloader.

Edit:
There are huge advantages by using RVZ over ISO, specially storage space wise, maybe RomCenter it will support RVZ one day too, that would make things easier for you. There are some archives in this platform that have gamecube ISOs sets, some are a bit outdated, but you can get the missing files from here and convert it back to ISO.

The RVZ can be reverted to ISO that matches with Redump dat, all you need it's to open dolphin, set up the directory where you put the RVZ files, which will fullfill the gameslist, then select the games you want to restore, right click, and convert to ISO, is not much different from extracting from ZIP files actually xD

Thanks for the comment ;)
For higher compression purposes, there are better options, but RVZ it's a playable format, so I didn't want to compromise the performance during gameplay.
That's why I went for the default settings, instead of using compression ratio level 22 or changing the compression algorithm to something else.
Zstandard provides faster compression and decompression performance than LZMA/LZMA2, I assume Dolphin takes advantage of that to unpack data into RAM.

Why 5 instead of compression level 22?

i'm actually downloading TLZ TP, and i'm curious to know if the files are completely safe.

@ChadMaster
Thanks for your reply! Do you plan on uploading any more CHD rom sets? I really appreciate your hard work :)

Mate whenever i verify the roms downloaded with the dat from gamecube you provided by redump.org i never get the green on romcenter. They never get recognized which will make it impossible to have updated when dats get updated aswell. They dont seem to be the real redump versions from redump.org dats, otherwise they d be recognized by the dat itself.

Edit: Thanks for it. Yah unlucky that's gonna be real bothering considering the gamecube set is one of the heaviest and everytime i would need to convert to iso everything in order to know what i miss when i want to updated.

LZMA and LZMA2 compression provides notable space savings over Zstandard when it comes to RVZ, but I'm sure you already know that. Thanks for your uploads.
