* AdLib/PC Speaker (early version) implementation of the

|
* sound output device.
|
|
*
|
|
* It uses a special sound file format special to EoB I, II,
|
|
* Dune II, Kyrandia 1 and 2 and LoL. EoB I has a slightly
|
|
* different (oldest) file format, EoB II, Dune II and
|
|
* Kyrandia 1 have the exact same format, Kyrandia 2 and
|
|
* LoL have a slightly different format.
|
|
*
|
|
* For PC Speaker this is a little different. Only the EoB
|
|
* games use the old driver with this data file format. The
|
|
* newer games use a MIDI-like driver (see pcspeaker_v2.cpp).
|
|
*
|
|
* See AdLibDriver / PCSpeakerDriver for more information.
