About LR2 extra mode: When activated, LR2 throws most background notes into the regular chart, making a way more difficult chart on the fly.
There are 3 levels of extra mode.
Level 1: Some background notes are added. Usually for 10th den players or up.
Level 2: More background notes are added. Usually for kaiden players or up.
Level 3: Most background notes are added. New chart typically consist of consecutive 8th notes (Like Mei SPA/ICARUS SPB). Usually for Insane BMS players or non-human players.

Which level of extra mode will be applied depends on regular chart's note count.
Level 1: 999 notes or less
Level 2: 1000-1199 notes
Level 3: 1200 notes or more
The application can be alters by a hidden menu, which shows up while pressing F2 in song list, for example: 1 2 3 to 2 3 3 OR 3 3 3

On some songs that contains less BG notes, like pre 4th style songs or key-sound-less BMS, this option will be useless,
while on some songs that contains too much BG notes, the new chart will be totally unplayable. (Mostly LED/Ryu songs, or songs like Illegal Function Call SPH or SPA)
