@dooklink - I read on shmups about people's comments regarding colours on Megadrive. I was wondering if there are similar things that apply to the AMIGA also apply to the Megadrive. As @Stedy's investigations a while ago found that some of the signals outputed were too strong for LCD TV's (but ok on original CRT) and he recommended adding resistors to many of the signals |
Can you link me to any evidence for the signal strength issue? I believe I know what the problem is, but I haven't measured the voltage levels yet.
Usually the chip has dynamic range expansion enabled. This way over saturates the Luma, ie brightness. The chip does all of it processing in YUV and converts back to RGB for that output type.
My settings should have the output DRE turned off, but there are other things that still need optimising. I'm just trying to determine if the problem is circuitry, ADC/DAC or Digital Processing settings.
