 ## Description

 ## PCSX2 Behaviour
 PCSX2 would swap FIELD unconditionally, this caused some progressive games to

 ## Findings
 The original finding determined that when the video mode is set to progressive, FIELD is set.

 Turns out, the SMODE2 interlace bit has no control over FIELD behaviour.
 
-The actual behaviour is determined by CMOD (bits 13 & 14 in SMODE1)

-When testing CMOD 1, odd VFPs should say `FIELD IS CHANGING`

-When testing CMOD 0, no matter the VFP, it should say `FIELD IS NOT CHANGING`
