If the directory is detected on the inserted Memory Stick, the game will refuse to start and therefore shuts off your PSP system, forcing you to reload the system.

As with most DJMAX Portable games in the series after DJMAX Portable International, In the retail version of the game, The game will perform an additional check on a real UMD drive to ensure if the game is present. if it is not present, Then after playing the game for a few minutes, the anti-piracy will; Add the crackles to the background music before becoming a distorted high pitched sound, randomize the playback speed of the keysounds and SFX audio, and/or flicker the graphics list to randomly skip drawing textures which causes the screen to flash rapidly.
