| Terra Cresta and later Nichibutsu drivers: Consolidate some common configs down into their own machine_config sections, and reduce a lot of code duplication. Also fix audio volume balance to compensate for the fact that the YM3012 Serial DAC for the FM chips outputs at half the peak to peak voltage of the R2R DACs, and the YM2203's SSG channels have another, different peak output level as well. This also adds filtered sound to Legion, which didn't have it in the previous commit due to the complex configs it had. [Lord Nightmare] |
