i dont even know what you mean, youd obviously have a million results if you just search for an 0 or a 2 by itself
Sorry for the confusion, I'll try to be a bit more detailed.
Step 1: Start a Mission, any mission will work but Kara's Restaurant will always be an unknown which will be a 0 so don't start with that mission as there are a lot of 0s to find which will take ages.
Step 2: Go straight to the computer and Mark as complete, this will display what the ghost in the mission was, however do not click again to go back to the apartment as this will reset the value we are looking for to a 0 which isn't helpful.
Step 3: Search in cheat engine with a number that corresponds with the ghost type, the number for each ghost seems to be in the same order that it is displayed in the Ghostpedia or Conclusion tabs.
0 = Unknown
1 = Kupper
2 = Shy
3 = Wiggle Wiggle
4 = Countlanak
5 = Bansheep
6 = Real Tall
I haven't seen any of the others ghosts or Bansheep spawn so for now you can use this as a reference. And also for people who haven't used Cheat engine (I'm using an old version but the process should be the same) you do your initial search by entering a value into the value field and searching with the "New Scan" button, you do any follow-up scans to search for value changes with the "Next Scan" button. The value you are searching for as of the current update is a "4 byte" and you want the scan type to be "Exact Value".
Step 4: Once the search is complete, end the mission and go back to the apartment, once back you can do another search for a 0 as when there isn't a ghost the number we are searching for should always return 0 but just in case its better to do the searching in a mission to make sure the number sets correctly.
Step 5: Launch another mission and repeat this process until you have a single value. Once you have a single value, either double click on it to add it to the bottom field so you always have access to it and when you enter a new mission, you can look at the number this address has to do the reverse of what we did to search for the ghost to find out what ghost your hunting.
I have no idea how to make pointers in cheat engine so each time you launch the game you will need to do this process again.
I hope this help and wasn't confusing, if you have any questions let me know.
