Sega Master System / SMS to jamma RGB a little dark
I have a Sega Master system converted to jamma. RGB is a little dark. I tap RGB from on IC labeled 315-5124
pin 26 = red
pin 27 = green
pin 28 = blue
pin 29 = sync
pin 32 = ground
I get about .2 to .5 volts (DC on multimeter)
If I switch to output of CXA1145. I see 2volts (dc on multimeter), but video is all washed out. And background that's suppose to be black is white-ish. any ideas on how to fix. I did a similar mod on my model 1 Genesis and it's nice and bright.
