I recently got an RGB CRT and I'm having an issue getting the mister to cooperate with it. I have a VGA to RGB BNC cable, if I use the Analog I/O board VGA output I get a correct image on the CRT. My usual set up is a CRT connected via S-Video so I was hoping to do dual output using HDMI to VGA adapter to the RGB CRT. I set up a secondary ini file to utilize for this set up and it's doing some odd things. I copied my main ini file to keep the S-Video out functioning then I changed the following lines
hdmi_limited=2 ; 1 - use limited (16..235) color range over HDMI
; 2 - use limited (16..255) color range over HDMI, for VGA converters.
direct_video=1 ; 1 - enable core video timing over HDMI, use only with VGA converters.
When I switch to this alt ini I get a normally functioning mister menu, color on the background image, menu looks the same. When I load a core the screen turns a reddish/brown hue. I have no idea what is causing this or how to fix it. I attached two photos to show what I'm talking about. I tested NES, SNES, GEN, N64, PS1 and a few arcade cores, all the same result. The only core I could get to function correctly was an old N64 build from January which didn't have S-Video compatibility so my S-Video CRT was showing a b&w image while the RGB was showing correctly.
I'm hoping this is simple and I'm just an idiot. Sorry for the low quality photos, it was late and I was tired from hours of messing around with the setup.
