| "Analog" Pokey Update [Couriersud] - Derived internal resistance calculation from Pokey documentation. This is a 4-bit parallel resistor (High-Z mos "devices") network to ground. The result is a non-linear resistance function. - Added low-pass filter support and opamp/resistor stages to the pokey driver. This is not as good as complete discrete emulation, but a lot better than the linear approximation we had before. - Changed a couple of drivers to use the new output volume calculation. - Added device configuration macros. Made all drivers use them. |
