Final Fantasy VI SNES - Ted Woolsey Uncensored Edition 2.03

I'm very interested in using this as a base for the patch I'm working on. Am I correct in assuming that TUWE 1.93 + Slattery Opera  is just that (no fixes or tweaks), and is therefore compatible with most other patches? Specifically, the version of C. V. Reynolds Bug fix patch that's hosted on this site (without the script changes)? Also, can this be used with FF3usME?

Exactly. I made mention of everything added in the Read Me for that purpose. It is compatible with FF3USME for the script at least. You might want to change other things in HEX though. Because some spell names were expanded slightly, FF3USME won't display or change them properly.
