Thanks for your very kind words, Rich! A lot of your suggestions are things that I've already done or intend on doing, such as the baseline and complete hack. When it's finally said and done, there will be 3 patches in the collection - a baseline patch for hackers to base further works on; a complete "vanilla storyline" patch, and a complete translation patch, based on the Lina Darkstar translation and the FF6A script.
So far I have had no issues with the ThiefKnife in my test playthroughs, and haven't heard of any. I am not currently using the Gogo/Paladin Shield patch, as it not completely optimized yet. I have not come across any graphical glitches, and so far I have not seen any issues beyond the one where the current version of FF3usME overwrites certain parts of code changed by patches, and a workaround is currently in place.
As far as an update is concerned: I have not yet finished integrating the translation into the Improvement patch, as there is one thing not yet complete - the Opera. The timing for getting the text to print with the singing is a little tricky, and I'm not yet satisfied with it. But I want to put this out soon, as over the next year I will have little time to work on any personal projects. Stay tuned!
