No.10662 sasuke Tester May 1, 2014, 16:55	I seems to solve this bug by the following change: (There may be a little error) lwings.c Line 768: MCFG_CPU_PERIODIC_INT_DRIVER(lwings_state, irq0_line_hold, 224)

If they are emulations, they likely are based on older and less accurate versions of MAME. The only real proof is to source and record the original PCB. Most of the settings in this driver for clock speeds and such have been verified to be correct with original readings from PCB. If you have access to any produced OST CD's, they can be used as a basic tempo/pitch reference as well.

Therefore, this value seems to have determined by the feeling of developers. And, I added some OST to Additional Information.
No.10685 sasuke Tester May 9, 2014, 16:35	I was compared to the Section-Z OST carefully. the exact value of MCFG_CPU_PERIODIC_INT_DRIVER is 221. I've uploaded the sound file for comparison.
