Publicised measurements of AY chip volumes - I've finally got round to However, there may be the need to change volume in certain drivers.Īfter what Russell mentioned a couple of weeks back about the lack of Samurai Shodown V Special / Samurai Spirits Zero Special (NGM-2720) Arcade.

If the voltages do not differ, well you would hear nothing. If there is a difference, it would mean that you hear something if a tone is output with e.g. The issue is most likely related to the output voltage of volume 0 (channel on) and volume 0 (channel off). Actually I have not seen a single arcade game yet using it. Time Pilot 84 (set 1) found in MAME ROM Set: tp84 Released in 1984 in the zip file tp84.zip.
