Treo 270

My wife just bought a new treo650 and no longer needs her treo270 so I thought I would find some games to put on it. I found some bit torrent sites that had pda games and downloaded them , but cant seem to get them on my treo. What type of file should they be in order to install them on my treo? From what I saw I think they whre jar files. I also downloaded activesync to my computer so that my cpu can comunicate with the treo, but it does not find the treo. Any info on this would be great... Is there some where else to get full version games on line for Free?
