Sound Voltex II: Infinite Infection

The game was released as an online update, one of the first BEMANI titles to do so.
Data carrying over from SOUND VOLTEX BOOTH consists of: player name (changeable), scores, clear marks, unlocked songs and play count of songs.
There are now hold notes on short buttons (LONG BT) and non-hold notes on long buttons (CHIP FX).
FX hold notes are now orange instead of dark green.
The song select screen was redesigned to go from a song wheel to a grid of jackets.
The INFINITE difficulty is introduced, similar to DanceDanceRevolution's CHALLENGE difficulty in nature. INFINITE charts have a rainbow hue.
PERFECT ULTIMATE CHAIN (getting 100% CRITICALs) has been renamed "PERFECT".
Similar to its beatmania IIDX counterpart, the "green number" (BPM x HI-SPEED value) feature has been added.
Failing songs with charts that have a difficulty rating of 7 or lower will not end your game session prematurely.
Charts rated Level 16 have been introduced.
Songs are divided into eight categories:
ALL (unsorted).
BEMANI (all remixed and original BEMANI songs).
EXIT TUNES (EXIT TUNES licenses).
ボーカロイド (all VOCALOID songs).
FLOOR (original FLOOR contest songs).
SDVXオリジナル (original SOUND VOLTEX songs).
東方アレンジ (Touhou Project licenses and remixes).
BLASTER (related to INFINITE BLASTER).
