Overview--------Contains a low-level OPL2 chipset access API used in old Adlib sound and Soundblaster cards for MS-DOS. The code still compiles with both Turbo and Borland Pascal 7.0 and the C code with Turbo C 2.0.It also contains sample CMF / SA2 players. The SA2 player was quite impressive at the time. The SCR player is incomplete and is buggy.This code is no longer maintained, patches/pull requests are accepted, but no other support will be given.Licence-------See docs/license.txt for the exact licensing terms. Building--------Simply build the units using Turbo Pascal 7 or Borland Pascal 7.Credits-------* FIRST AND FOREMOST Jeffrey S. Lee for his documentation on the OPL2 Chipset found in the Adlib Sound Card. * SBFMDRV Tracing to find out how to calculate the SemiTones and Note modifications.* The person who gave me the original idea of starting this project: Ezra Dreisbach with his C SCR FM Player.* All information on the SA2 file format was taken from the SADT2 document which was created by Erik Pojar* All information on the CMF file format was taken from the PCGPE magazine which was created by Mark Feldman. * The PIT Interrupt was also taken from Mark Feldman and his great PCGPE encyclopedia.Enjoy!Carl Eric Codere
