Dxr3 - Parameter

General fixes:

em8300:
  activate_loopback   -- set to 1 if you lose video signal
                         when uploading the microcode
  bt865_ucode_timeout -- set to 1 if you have a bt865 and get timeouts
                         when uploading the microcode.
  use_bt865           -- set to 1 if you have a bt865.  Modifies some
                         initialization values.
 This now works with multiple cards, so you can
                         do use_bt865=0,1 if you have two cards and the
                         second uses a bt865.

bt865:
  rgb_mode            -- set to 1 to enable RGB output
                         (requires hacking DXR3 hardware)

  color_bars          -- set to 1 to enable color bars
                         (only used to test the chip)

If your red and blue colors channels are switched:

adv717x:
  swap_redblue_pal      -- swaps the red and blue channels (ntsc and pal now)
  pixeldata_adjust_ntsc -- If your red and blue colours are swapped in NTSC,
                           try setting this to 0,1,2 or 3. Defaults to 1.
  pixeldata_adjust_pal  -- If your red and blue colours are swapped in PAL,
                           try setting this to 0,1,2 or 3. Defaults to 1.

Greenscreen (tvout only) fixes:

adv717x:
  pixelport_16bit     -- use 16bit pixelport control
  pixelport_other_pal -- use the opposite pixelport control for pal mode
                         if you only use/care about NTSC or PAL ignore this

em8300:
  dicom_fix       -- set register 0x1f5e to 0x1efe instead of 0x1afe
  dicom_control   -- set dicom control register to 0x9efe instead of 0x9afe
  dicom_other_pal -- use the opposite fix values for pal mode
                     if you only use/care about NTSC or PAL ignore this.

Common settings to fix greenscreen:

  adv717x pixelport_16bit=1 pixelport_other_pal=1
  em8300  dicom_fix=1 dicom_control=1 dicom_other_pal=1

  adv717x pixelport_16bit=0 pixelport_other_pal=0
  em8300  dicom_fix=1 dicom_control=1 dicom_other_pal=0

  adv717x pixelport_16bit=0 pixelport_other_pal=1
  em8300  dicom_fix=1 dicom_control=1 dicom_other_pal=1

  adv717x pixelport_16bit=1 pixelport_other_pal=0
  em8300  dicom_fix=0 dicom_control=0 dicom_other_pal=0
