This is some great stuff. Kudos to you all for the effort in undertaking it.
Now what I'm about to put forward isn't a complaint or an attack, just a question. I recently ripped the Super High Tension model from the US PS2 version of Dragon Quest, and I've been trying to recreate it to the specifications of the 3DS version. I've already gone through the thread, and I know for a fact that someone already said that "it's impossible to insert a fully customized model to the 3DS version".
I'm not going to ask any of you to do this, but as long as it's possible someday, I can keep working at importing the US SHT model, to truly recreate the North American version, or at least add one more element to recreate the experience. Even if I have to make such a tool. So what I'd like to know is if it's truly impossible, or simply impossible with the tools that currently exist to us, and a tool just hasn't been made yet? If it is "truly, technically impossible no matter what tool you make", then I'll accept that and just give up.
