Ok well I didn't get far

I don't know how to add preferences for which video plugin to use in the surreal.ini file. Does anyone know what the command for this is? I'm sure there must be a command for it because there are command for every other preference.
It's easy for the other preferences, they are as follows:
Preferred Emulator=0 (1964)
Preferred Emulator=1 (PJ64)
Preferred Emulator=2 (ULTRA HLE)
1964 Dyna Mem=x
1964 Paging Mem=x
PJ64 Dyna Mem=x
PJ64 Paging Mem=x
Max Video Mem=x
Use Basic Audio=1 (on, 0 off)
Use LLE RSP=1 (on, 0 off)
I've also found these commands from another thread which aren't really necessary but might be useful for games with very touch controls (like goldeneye):
NPad Deadzone=2015
XPad Deadzone=0.37
XPad Summand=0.01
I'm not sure what they mean exactly. Deadzone makes sense, not sure about Summand? Anyone?
Can't really start the ini file until I know what the commands are
