maimai DX:Friend Matching

Friend Versus has a dedicated folder in the song selection screen. Inside this folder are several randomly chosen charts. When a chart is selected, the strength of the opponent (the rank of the high score that needs to be beaten) is shown. The player would participate in Friend Versus only if the player chooses a same or higher difficulty than the randomly chosen one; if a lower difficulty is chosen, Friend Versus will not be enabled for the track. The strength of the opponent depends on the current 段位 (DX1 ~ Splash) / Class (since Splash+) of the player.
In multiplayer mode, either player's charts can be used by both players to enter Friend Versus.
Friend Versus has been revamped in Splash PLUS. For description of the mechanic in Splash and before, see /Splash.
