Any way to Edit the Text?

Alternately, you could ignore the editor and do text-editing the old-fashioned way that the hex-editors of the past did and apply ascii tables to the rom in a hex-editor like WindHex and change it manually, thus making -sure- that you don't overlap any stray map data.

If you DO choose this method, do keep in mind while it is, indeed, surefire... it is very difficult, and one minor error will likely screw up a string of dialouge. Been there. Done that. I've got Kendo (Renamed 'Swdtech') and Lore all over my Skills menu page. Ffff.
