Interplay Entertainment (formerly Interplay) is a game developer and publisher formed in 1983, and it was based in the United States. Initially focused on computer games, the company changed its hands starting in 1990 when Interplay developed console games, and in 1991 became a full-time publisher of both console and computer games.


Music Development


The company used David Warhol's sound engine from Realtime Associates. However, for the games Star Trek 25th Anniversary Edition (NES) and Trog! (NES), Interplay used their own custom driver programmed by Rebecca Heineman. Her driver was MIDI-based like Warhol's, and allowed users to create their own instrument patches.


The name of the sound engine is Advanced Real-time Dynamic Interplay (ARDI for short). The first version of ARDI, was programmed by Rebecca Heineman (who would later go on to program her sound driver, with John Carmack in Wolfenstein 3D (SNES) and Super Noah's Ark 3D (SNES), featured a SPC file that is dumped, and it was only used in RPM: Radical Psycho Machine Racing (SNES). The second version, which does not dump SPC files, and instead used SNSF files, was programmed by Jim Sproul and John Phillip Britt. Sometimes, games developed by Interplay used either Visual Concepts or Sculptured Software's sound driver.


Interplay programmed two versions. One version is programmed by Rebecca Heineman, was used in Track Meet (GB). The second version, which was probably programmed by Scott La Rocca, was used in Star Trek: 25th Anniversary (GB).


Most games used either GEMS or use Shaun Hollingworth's driver.


Brian Schmidt wrote MIDI files which were converted into his sound driver.
