In addition to developing games, Shin'en created the soundtracks for around 200 video games by other developers, and built the GHX, GAX, DSX, and NAX (which is based on the GAX) handheld audio middleware.
Their name is derived from the Japanese word 深淵 (shin'en, "abyss"), as a nod towards their original name.
In addition, Shin'en has developed the audio of hundreds of games on Game Boy Color, Game Boy Advance, Nintendo DS, WiiWare and Nokia N-Gage as an outsourced audio developer, using their proprietary audio engines.[5][6]
