Here so I thought that Heavy Rain can't be played on my ps3 because I have a BUSTED bd drive. Because I cant put disc on bd drive and I cant move it to internal since I only got 40gb which is nearly full .

BUT .. when I check the ps3 compatibility list here's what I got.

Internal-Yes
External-See note
BD Mirror-Yes
Ebootfix-Yes
DISCLESS-See note
Updates-Yes .

Notes:

To play discless run a rare special fix pkg, then shadow copy the game (44259661...1122223333(dot)pkg) To play from external w/o BDMirror: install from disc, then play from external.

I dont quite get what that means , and I cant seem to find a link of the pkg . Most are uploaded on Megaupload which is now been taken down. And whats up with the "install from disc" thing ? I need help please.
