Summary	03589: mystston, myststono: VSYNC does not match original PCB
Description	Vertical sync measured on the original pcb should be 57.4hz instead of 68hz. In mame vsync is derived from a calculation of pixel clock and total resolution (not the visible one). Since the pixel clock is reasonable (12mhz/2) I think the total resolution is wrong. I think the regression is this: - 0.123u4: Mysterious Stones gets the "full treatment" [Zsolt Vasvari]. Changed VSync to 68.933824 Hz and palettesize to 64 colors. Before it was correct: - 0.113u2: Changed VSync to 57.444853 Hz.
