Stiebler is correct, I was assuming an 8k over existing 8k, you may have to adjust the following or replace with stock or another 8k version.
In the
data\Cfg folder:
Contacts.cfg
Sensors.cfg
Sim.cfg
In the
data\Library folder:
Sensors.dat
AI_Sensors.dat
This of course includes the Scene.dat & the 6 sky & sea Env files (part of my 8k mod), not sure if there are any others.
PS. Sorry if I'm stepping out of bounds here Stiebler.
