Sorry about the dbl post, but I guess the only way this may be noticed is an increase in the # of posts, and not another edit. Anyway, in addition to the questions and stuff above, I managed to get one of my video cards down from 29Khz HSync to 17KHz Hsync. Is this enough for the RGB mod? I ask because it is close to 15KHz, but not quite. It is on 640x480 Arcade setting.
