With better understanding of .bin files and the default.xbe file I was able to improve on 'porting' Tengu to DOA3. Still not 100% working, but a lot more playable now.
Now has proper wall-splat ranges on the right attacks. No more cameras being triggered on certain attacks. Functioning wall throw. Almost functioning edge throw. Functioning holds. Haven't touched Close Hit and Far Hit yet, but I know how to get those working too.
Currently, his down attacks are not working correctly. He can input them, but they do not trigger the proper animation on hit. He also does not have the higher jump arcs that he has in DOA2.
