I have tested the Shadow leaves a one-man party and Airship/Game Over exploit using your complete patch, and both bugs appear to be fixed. I also looked at the descriptions for all 255 items, every magic spell, esper, lore, etc. and didn't see any bugs. I did see a bit of weirdness when talking to someone in Narshe though. There's a guy who has a word censored with symbols in the normal game, but those symbols are replaced with the wrong letters in the hack. Two screenshots are attached, one showing what it looks like in the hack, and the other showing what it looks like in the unhacked game. It looks like the @ and the % were replaced by the letters i and l respectively.
EDIT: I found another minor visual error in the Bushido list. Some of the Bushido names seem to be not aligned properly. The third screenie shows what I mean.
