DJMAX (also known as DJMAX Emotional Sense) is a music video game for PSP and PC, created by the South Korean company Pentavision Entertainment. Online version was released in 2004, and single-player version of the game for the PSP DJ Max Portable has been released in January 2006. On March 30, 2007, Pentavision launched DJ Max Portable 2 (containing 60 songs, and more than 150 songs in OST mode) which includes disc link, fever mode, and new features such as items.
In 2008, two new games in the series have been announced. The first is DJ Max Fever, a combination of both DJ Max Portable and DJ Max Portable 2, made for release in the United States of America for the PSP, and is the first in the series to do so. The second is DJ Max Technika, an arcade-only game that will have a top screen for spectators and a bottom touch screen and play like Osu! Tatakae! Ouendan (known in the US as Elite Beat Agents). This will also be the first DJ Max game to have songs with Music Videos that have fully rendered 3D graphics (excluding Whiteblue, the opening to DJ Max Portable 2 which has the song Your Own Miracle, and A.I.).
DJMax is currently in service in Korea, Japan, and China. The three different versions also have local songs(generally, popular songs of each country). Service in Korea ended on March 21, 2008, while the Japanese version was discontinued 10 days later on March 31.
