FF6 - Brave New World

1: Locke's red dot below his ear that doesn't look like an earring is still there.

Did you patch over an older version? I don't see the issue you're talking about when I patch 1.0.4 to a fresh ROM.

2: Edgar talked to the Figaro Castle merchants himself, then I put Sabin in the lead, but the bros are left with but one question: "Where's my royal discount?"

No more royal discount. Both Figaro brothers should admonish the merchant for suggesting it.

3: In Kohlinghen, the woman who asks if I'm a friend of Locke is able to walk onto a space off the map to the left. (It's a black space.) If I move there, I leave town.

We didn't mess with any NPC movement patterns, so this was likely the case in the original game too. It seems minor enough.

4: Kohlinghen: The weapon/armor/item shop is called the General Store. In other places, the item shop is called the General Store. Was curious about the why of this naming decision.

Same as #3. We changed the text on some of the location names, but didn't change what locations used them. "General Store" was "ITEM SHOP" in the unmodified version.

5: Setzer's ship: "The Empire... evil?"/"The Empire's made me a rich man!" I miss these classic lines.

It didn't make sense from a narrative point of view that Setzer is on the Empire's side considering how quickly he turns on them. On top of that, the way it ended up originally was a product of shoddy translation; in the Japanese dialogue, he's upset at the Empire for ruining his business.

6: Albrook: I enter town and there are green translucent overlays on some of the scenery. It just looks weird.

This might be the same issue as #1, as I can't duplicate it either.

7: Zozo: Did y'all program things so if Celes goes before a Slamdancer, the Slamdancer doesn't use a Runicable ability? It happened at least 3 times. Also, whenever Celes went after a Slamdancer, the Slamdancer cast Fire.

Nah, that's just shoddy luck with the RNG. She doesn't really start favoring magic attacks until she's all alone either.

8: Tzen: In town, I walked directly left and went 'behind' the gray stone. The stone's color turned darker because I was there. Odd. (May've been in the original game.)

Sounds like an emulator layering issue, like when you see characters' heads detach from their bodies during battle events (like the first Ultros battle). We didn't do anything with Tzen's map, so you're probably right about that being a relic from the original game.
