DoA3 modding

In 3.1's default.xbe, the value for the combo_limit at 0xA8633 is 0xIE (30). You can change this to 99 or FF or whatever and actually make Bass's infinite combos be infinite. The ram address equivalent is 0xB8633 in case you want to use Cheat Engine.

Am I reading this right? Are there are slots for seven more characters' win quotes after Bayman? There might be space already.

Yeah, I keep finding references for an extra seven character slots after Bayman (see below). Super interesting that 0xF (Indian Belly Dancer or K-1) has their own unique dataset here. Normally deleted characters have blanked out data but there's some leftover here. I'm not sure what this data is yet (it's minor, only a couple bytes) but it seems like work on slot 0xF continued on from DOA2.

It's interesting that 0xF is using Kasumi's skeleton data. 0xF is the deleted Indian Belly Dancer in DOA2 (which used a lot of Kasumi's data as placeholder) but in DOA3 0xF is listed as "K-1" and would later become Lisa/La Mariposa.

So, "Hakkyoku-Ken" aka Kokoro was in development since 3? Interesting. But there's another Pro-Wrestler character in the development? And who is "Tekondo", and "Chin"? Demi Human sounds like Raidou again.

 

[Gultigargar]

"Chin" is Brad Wong's master that shows up in a cutscene his story mode. He's not really properly playable, but I guess for whatever reason they needed to give him an ID he could use for those in-engine cutscenes.

I found the movelist stuff in the beta version. It should be easy to find in 3.1 and now might be possible now to add moves to the list. Would be useful for 3++'s added moves.

 

[Gultigargar]

That's really cool! From that I can now at least see the structure of how the command list is put together. We can't add anything to it, but we can at least modify what's already there. So we should be able to update mid kick holds to display a input.

I had already sorted 3.1's data, I just hadn't labeled it. I'll work on that today. It's interesting seeing the changes between the beta and 3.1 (Christie's 46P used to be called "Hineri-Straight-Zuki" but in the final it's "Dokuja-Bunsho"). For an accurate diffing, I should be comparing the beta and 3.0 but I already had a 3.1 project going.

Here's my WIP Ghidra projects if anyone wants them. I've sort a lot of data but I've still only touched the surface of an ocean.

They were considering replacing everyone in DOA3 at one point, with Hitomi being the new lead heroine.

Hitomi appeared in "DOA3", but it was supposed to be the leading role when planning to replace all the characters. https://www.reddit.com/user/penmast...story_of_doa_hitomi_bayman_leon/?ref=readnext

Labeling more sparring stuff in Ghidra today.

Edit: ta-dah! Hey, what do you think this data in between could be for?
What does Zack have 172 of in the beta that he has 186 of in 3.1?

Edit2: Notation differences are interesting.

Lots of DOA2 assets on this list.

Lots of DOA2 assets on this list.

Yeah, surprisingly, they don't crash the game. Rather, you just get a blank black stage.

I wonder how hard it would be to port the DOA2 levels back in, seeing as how the slots already exist.

The 2U stuff is in a newer format, it'd require reworking the data, but it might be possible.
