I mean you can avoid all that. If you're just interested in music and retro games then just use soulseek and use the rom megathread. both of which are going to be either peer to peer or direct downloads. no torrenting.
Rom megathread (web search it) has quite literally everything. no need to search, no need to torrent, it's all right there. And soulseek with Nicotine+ just works like napster. sign up, be sure to share your music library, and then have at it.
