Pandora's Battery is much too confusing! It took me 5-6 hours, to figure out what I was doing!Find an copy of Lumines.

oh sht my bro traded back his lumines ages ago and does it have the upgrade to 3.50 so if i manage to get lumines i also need to upgrade to 3.4 soo i wonder wat game?And i got a couple of friends of that has custom firmwares but i still dont get how to get pandoras battery... yea how the hell u get one anyway.And.... Lumines unpatched? wats with the unpatched i dont understand?

Well Once They Found Out You Can Use It To Downgrade They Patched It So The New Ones Wont Work, Just Rent It From Somewhere Or Ask Your Friends
