Any way to Edit the Text?

Hey guys I was wondering if there's any way to edit the text in the game without getting a blank screen on the world of ruin if you use Final Fantasy III Level Editor? I used FF3usME to edit the text but whenever I load WoR, via Level Editor, it's just a greenish, blank screen. I looked around, but finding anything concerning this topic is impossible, save for this site. :p but I could really use some help, any program name that works to edit the text and doesn't cause collision at WoR is awesome! (I shoulda listened to Zeemis on his Youtube vids ha)
