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).
