In internal HD the games are backuped to GAMEZ folder too, if you acess your HD you can see that. Try acess your internal HD by FTP, like show that:
Gaia, multiman, Rogeros, are good mangers, but Gaia still not suport lv2 patche automatly.
Multiman have a interface that allows you see your HD internal files and folders, it a good option to see the files, but not allows you modify like FTP.
i hope this helps you.
You can install all of them and
