Changes

Most of the DOS games make use PC-9801-26(K) which provides 3 channels of FM, 3 channels of PSG, or PC-9801-86 which provides 6 channels of FM, 3 channels of PSG, and PCM recording & playback.  For Windows, PC-9801-118 provides support for both FM and PCM playback as a PnP & Windows Sound System compatible card, but not fully backward compatible with PC-9801-86 under MS-DOS. Q-Vision WaveStar is yet another PnP card for Windows but is fully backward compatible. Alternatively, games originating from IBM PC such as Doom may have the option to make use of Sound Blaster 16.
