|Summary||06201: cpcp464p, cpc6128p, gx4000: Monochrome monitor is not monochrome|
|Description||In current implementation of this driver, setting the monitor to monochrome (which was normal factory option for these), actually just changes background to light green, while KEEPING all the colors enabled!|
|Steps To Reproduce||Set monitor to monochrome in system configuration, run a game (like Amstrad stock, Burn Rubber). Background remains a (fake) green (no monochrome monitor produced this green) and all other game colors show normally (red, blue etc.).|
|Affected Sets / Systems||cpcp464p, cpc6128p, gx4000|

Get me some example pictures and comparisons?
There was recent discussion regarding it here:

What kind of example pictures? I don't have a real green monitor (or a CPC for that matter).
I am not sure of the proper way to make it work (it could be just stripping R and B signals, it could be retaining luma and stripping chrominance. Don't know.
NOTE that CPC464 and CPC6128 (non-plus) models work properly in green mode.
In other words this BASIC program (sorry never owned an Amstrad CPC):
10 MODE 0:PAPER 0:PEN 1
20 FOR i=0 TO 26
30 INK 0,i
40 LOCATE 10,12:PRINT"INK";i
50 FOR t=1 TO 400:NEXT t,i
60 MODE 1:INK 0,1:INK 1,24:CLS
...will produce green hues in CPC464/6128/664 with set monitor green, but will still produce colors in CPC464+/6128+/GX4000.
