Resident Evil 2 Partner system, Mhmm

Hey guys,
Me again. Yes i am doin stupid amount of things the same time, I get bored easily. Im trying to work out what determines your partner character(ada/cherry) to be enabled. Ive noticed that when you trigger the partner, it loads up the NPC like it would loading up any other enemy. But when travelling to another room, that file is not loaded again. Ive even had the partner character follow me to a completely different room, like the streets. So obviously this partner can follow you anywhere through the game. I believe that there is going to be a trigger switch somewhere which determines whether your partner is there or not. Only problem is causing the character to be loaded in the first place.
Additionally, there is a variable somewhere which determines that the partner character cannot harm you. Ive changed the partner to mr x, he did appear like he wanted to kill me (So his AI is determined from his EMD).
Ive also noticed that the ai partner doesnt load up a PLW for its gun.
Anyways, I really need to work harder and plan it better.
Thanks

00, 01, 04, 08, 0C, FF are normally the 1byte values to switch things off/on an on in a game you should experiment with a program like Artmoney or Cheat Engine.

just run it on a emulator or preferably the pc versions
"Unknown initial value" search, move about then do a "Equal To" search to elimination addresses that constantly change around then do a "Not Equal To" search when you switch to a room with the partner keep on going in and out of the room to eliminate more addresses till you find the one you need, i'd start with the room where Ada is injured and lying down since she won't follow you.
As for partners with guns your gonna probably need to remake the PLW for each NPC / Partner the only platforms that allow you to use weapons with partners without modification is Nintendo it must be something to do with the file formats they use cos it's the same case for RE2-RE4 on the gamecube, RE2 on the N64, I haven't checked remake or zero but I bet it's the same too it's kinda odd to say the least

A simple 22byte value inside each RDT determines this... as already known, not every RDT will have this value.

Using my shitty RDT extractor, it will spit out a file called ROOM*.SCE (that is, if no filesize/offset calculation errors occur). This file contains information as to which enemies/characters are present in a room, as well as door, text inspections, etc data, their x,y,z loc, everything.

Do they have a 360 degree bent turning circle rotation as well? for leaning over and falling backwards, I'm guessing it would the 18 and 19th bytes.
