Well...as for the bugs above...
Yes...I liked the way those treasure chests turned out too...except that was a compromise. I was trying to change them back to the way they looked in Final Fantasy IV normal...but it didn't work...I can't remember why not...so I did that.
Not sure what's going on with that item drop...could be collateral to using Yousei's editor...?
The trail near Troia castle was just superficial to the dopey tower of zot wannabe I put there...LOL I was really just playing around with the map editor.
The general consensus in other FF4 circles, including the Japanese, is that Zot is a high-flying floating fortress left by the Lunarians at some point in the past (the idea I've heard is that it was supposed to have been an observation platform used/built by KluYa or FusuYa to keep tabs on events on the Blue Planet).
I'm slightly disappointed that you can't buy Charm (and to a lesser extent, Samurai/Yoichi's Arrows) in the hack.
The biggest plus is selling the Glass Helmet.. making Edge take far less damage in the Giant.
I think the Charm Arrows will probably be sold somewhere in future hacks. I read your post about tweaking the arrows and bows, and those are great suggestions I will probably use some of that.
Samurai/Yoichi Arrows should be normally sold by Kokkol along with the Shuriken and Ninja Stars/Fuma Shuriken after you have him forge Excalibur.
