EIM (有限会社ＥＩＭ EIM Co., Ltd.) was a Japanese game developer who was founded by Kenji Eno (pronounced E-no) at the age of 19. Eno had previously worked at Interlink as a composer. Eno was required to use licensed characters (due to contracts), which ended up making him mentally unstable, and he closed the company's doors as a result. The company developed primarily only Famicom titles, though produced a couple arcade games.
The company's initials stood for Entertainment Imagination (and) Magnificence.
Kenji Eno and Hirohiko Takayama were the only composers for EIM. They used a sound driver by Michiya Hirasawa. It is unknown how they created music and sound for the Famicom, but it was most likely either assembly or Music Macro Language.
