Can't get Phantom Hourglass to work with my G6 lite

I am using trim, and safe mode with the latest firmware. Should I be doing something differently? When I boot up the game it says something like: data cannot be read, please reinsert game.Please help.EDIT: Oops, I might have wanted to put this in the technical help section. Sorry, I don't know how everything works here yet. Could someone point a mod in this direction?

1. Try a non trimmed rom.
2. Try the arm7 fix.
