|Deep into the Code
Deep into the Code is a song from Doom series which was composed by Bobby Prince who wrote the track in Sequencer Plus Gold with apparent musical inspiration from Slayer's Behind the Crooked Cross. Prince's mental inspiration came from watching Doom's lead programmer, John Carmack, working on the Doom engine very late at night.
Bobby Prince had this to say about the track:
If everyone at id Software worked as long and hard as John Carmack, id Software would be absolutely untouchable by any competition. Everyone else at id Software would answer this by saying that they have a life outside of developing games! John would answer that he does too, but he'd rather be programming all of the time :) The reason I bring this up is that while I was at id during the development of DOOM, I stayed in the office many, many hours myself (after all, that's where all of my transplanted music toys were located). As a result of long hours at the office, John and I were often there at the same wee hours of the night. John would only leave his office to nab a coke or run to the mens room -- that is except when he had something special programmed and wanted someone to see it. Those kinds of things happen a lot around John, too. He is always coming up with some cool addition to his engines. Many times in those wee hours, I would come to a point where I couldn't make positive progress toward completing a song or a sound effect. I would go out into the then main room where a pool table sat and just roll the balls around the table. I could look into John's office and he would be sitting there in a world of his own, oblivious to anything else going on. When I worked on this song, I took a break at the pool table and saw John working away. That's when the name of this song hit me.
This is the original port of Doom where Deep into the Code appears. It is played in E3M3: Pandemonium (and in E4M3: Sever the Wicked in the expansion pack, Ultimate Doom (DOS)).
This track's internal name is "D_E3M3" and it is not included in the shareware version of the game.
Deep into the Code, in the Game Boy Advance port of Doom, plays in the same level as in the PC DOS version, Level 18: Pandemonium. This is curiously the first song to play properly on a level where it should do without any "shifting" to the next song.
This is the only song used in a home console version of Doom. The other ones rather play different tracks like On the Hunt.
