Why not use myrient? It seems to have every ps2 game individually and is also easy to mass download from (at least with a download manager) and the speeds are great in my experience.
Great speeds? Using Jdownloader2 if I go above 3.8MB/s with more than 2 connections I get throttled to worse than dial up speeds.
Occasionally it'll hit a single game that'll take days to finish for no apparent reason no matter what. It's maddening.
Still better than archive.org's broken fucking torrents that'll never ever reach 100% completion. You'd think an archival site would care to fix that after YEARS for FUCKS SAKE, but nope!
Nothing special about it. It's just an aggregate/repack of the smaller torrents that broke them out by letter groupings. They're the same exact files otherwise.
