FF6Tools - Browser-Based ROM Editor

Also, event based entrances seems to share unintended data like NPCs and probably other stuff.

For example, if I mess with the NPC that sells goods in Phantom Train (map 145) and save it, he will appear in both instances of that map (2 wagons uses that map but have different NPCs, entrances for both instances are events). I modified one of the NPCs in Map 151 so he become a seller as well (just by changing script pointer to CB/AD44) and he appears in both instances of that map when he's not supposed to.

It is a bug with FF6Tools or there's something I'm not doing correctly? I never had to do anything else with FF6LE and ZoneDoctor so I wonder what causes this.

Interesting, I'm not sure why the same NPC would show up on two different maps. It sounds like it might be a problem with the pointer table. I made some pretty major changes to how pointers are calculated and stored just now and I'm hoping it might solve the problem you're having. It's now live on my GitHub page (I also added the FF5 battle editor).

It will also now prompt you to expand the ROM when needed. For now, it does all of the data relocation automatically, but I might eventually add some options to let you specify where to move stuff to. This will potentially cause compatibility issues with other editors, but it allows you to add as many triggers as you want. You'll need to use the default definition file to get the auto-relocation stuff to work, and I've only added it for FF3us and FF2us so far. Let me know if you find any more bugs!

BTW, I had to make a few changes to the definition file format, so you might notice some issues when opening a previously saved ROM. Let me know if anything gets really screwed up and I can try to help you salvage it.
