From e95d109605727db68566265d79a4982fffca9b71 Mon Sep 17 00:00:00 2001 From: birdybro Date: Wed, 23 Nov 2022 20:34:07 -0700 Subject: capcom/sonson: Change vsync to 55.40Hz (#10537) Source of measurements --> https://github.com/MikeS11/Arcade-Sonson_MiSTer/issues/1#issuecomment-1312089702 The value originally set must have been a typo, according to @kold669 (aka Corrado Tomaselli). The original PCB alternates between 55.37Hz and 55.43Hz and it is Corrado's suggestion to run it at 55.40Hz. --- src/mame/capcom/sonson.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mame/capcom/sonson.cpp b/src/mame/capcom/sonson.cpp index f38715bc305..02141c42598 100644 --- a/src/mame/capcom/sonson.cpp +++ b/src/mame/capcom/sonson.cpp @@ -440,7 +440,7 @@ void sonson_state::sonson(machine_config &config) // video hardware screen_device &screen(SCREEN(config, "screen", SCREEN_TYPE_RASTER)); - screen.set_refresh_hz(57.37); + screen.set_refresh_hz(55.40); screen.set_size(32*8, 32*8); screen.set_visarea(1*8, 31*8-1, 1*8, 31*8-1); screen.set_screen_update(FUNC(sonson_state::screen_update)); -- cgit v1.2.3
