I don't think I'll really need help testing, since I haven't encountered any bugs. If you want though, you can try hacking the item and skill structs. Can't reinsert those since... well they basically don't function the same as the dialogue.
The /Abi folder is where you'll find skills.
The /Itm folder is the item list.
The /Sgi folder is also a skill folder (probably enemy skills)
If you want the code that dumps these, well I can post that, but it's only really useful if you're interested in trying to hack the game. All written in PHP.
