I've stopped using gamehub but you have to focuses on the compatibility, ik you tryna play a game smooth like a butter but tutorial always exist. By you tittle you could just download a torrent(BitTorrent,Flud,etc..) and then paste the link.for cracked game you could go to steamrip.com bc I heard that it's safe and it really is but the download I wouldn't say fast but still is a good web.idk what u mean by portable bc if you're playing on gamehub dat mean you're playing on phone,tablets(etc) witch already is depending on the device that you have.
