To summarize:
Search for string CEWP
Higlight "P" in CEWP and add next addresses:
+7 - position1
+B - postion2(how high object is)
+F - position3
+16 - rotation1
+19 - rotation2
Sometimes you'll see ID's like AKIR or TAXI that can help you to identify who is who or what is what, sometimes you'll just have to guess , some addressees doesn't work at all.
It's a little difficult to explain so I made a video:
In Dobuita additionally to "CEWP" there is "D000" for people and transport, works the same way as "CEWP" with difference that these seems to be a spawn points coordinates i.e point at which objects will appear when Ryo approaches them. Also I have found that there's almost no Id's to work with, so you'll just have to guess which is which..
addressees are :
+17 - position1
+1F - position2
+41 - rotation
It work best with characters standing still like Tom or Nozomi..
In addition to all that, if you change all D000 to JD00 you can move all characters from Dobuita to Sakuragaoka, video will explain it all
There's still things to be figured out, but for starting point this will do, i think
As an example I made this Cheat Engine table with some objects for Sakuragaoka https://www.dropbox.com/s/6ogms49bis6oe ... ka.CT?dl=0
This one should work for PAL Shenmue 1 disc 1
