JPAN's save block hack frees up saveable ram space. Without it, there is no room for you to put all of your stuff. It doesn't remove anything but the help menu. It more consolidates little bits of free space from everywhere into big chunks.
Yes, I do, but Knizz has a newer version than I do, so I would go on RHO IRC and ask him for the link (or maybe the link in his sig is up to date, Idk).
