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
