ccodere / pascal-adlib Goto Github PK

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This code is no longer maintained, patches/pull requests are accepted, but no other support will be given.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.
