Mental Outlaw explains privacy in a simple way, there are legit service that have proved their good and bad relationship with their users.

Like proton and telegram will give out your IP address

Others may not

The idea is that RetroTorrents allows downloads through torrents, while Vimm doesn’t.

Yeah, is there is a better platform perhaps?

I just put a quick description in this post, I will add a “what” section when I can.

(It sounds brilliant but) No, its a website like the pirate bay, nowhere finished atm…

RetroTorrents.net has magnet links

1 magnet = 1 Compressed ROM

Use a torrent client

Download compressed ROM

Play the game

Seed the torrent

No need to decompress a .7z or .zip file from vimm or myrient, the ROM file is already compressed and ready to play.

Can’t tell you right now.

PHP can be old but it is still taught at schools, are there other languages I should use?

There are unofficial search plugins for qBitorrent here and they work well

But I prefer using torrents-csv.com
