I've been searching for a solution to this exact problem. My partner sends links occasionally and I always ignore because of how the web interface is blatantly hostile. Tried routing the links through MPV on android but no dice.
If anyone has a solution please share.
Anecdotal, but when I was just messing with qBittorrent and its search feature, I found some ROM sets just by searching for system and sorting by size. This torrent for example is not necessarily comprehensive but contains a lot of roms of which can be shared with friends and family :)
