Changes
/* PlayCity: Partially compatible */
The Play2CPC does not have a CTC chip, as opposed to the PlayCity which includes a CTC chip. The Play2CPC use the default configuration of most of the PlayCity programs, like ALCON 2020.
Sound capabilities are also quite different. The Play2CPC is equipped with an OPN3 (ymf288) soundchip. It offers 3 PSG chans, 6 FM chans and 6 adpcm rhythm digidrums chans.The PlayCity is equipped with 2 PSG soundchips offering a total of 6 PSG chans, but zero no FM and adpcm rhythm no digidrums chans.
So the few PlayCity programs using 9ch AY will be not replayed by the Play2CPC.
