# Settings that we can tweak from the server.
# There's a variety of settings that the game supports, not all of them are figured
# out. They are documented below.
#
# "MAL": 1 - Unlock all DLC levels.
# "MO": [<levelnum>, <levelnum>, ...] - unlock certain DLC levels by ID. The four
# DLC levels are as follows:
# 14 - Morse Code
# 51 - PiroPiro
# 60 - Pop'n Music
# 61 - Love Drop
# "CM": "Arbitrary String" - Scroll the message "Arbitrary String" in attract mode.
# "IM": "Arbitrary Message" - Display "Arbitrary Message" on a new bulletin in attract mode.
# "ALL": 1 - Force-unlock all non-gacha characters.
# "MD": [<int>, <int>, ...] - Unknown setting related to demo mode. Possibly allows server-selection of
# which levels show up?
# "MQ": 0/1 - Unknown boolean setting that enables recommendation weights I think?
# "MR": [<int>, <int>, ...] - Unknown setting related to recommendation weights. Only appears to be used
# if "MQ" is set to 1.
#
# Additionally, there are a series of settings that are related to character unlocks and BGM selection.
# I haven't figured out what this setting does, but it might enable gacha-pulls of characters that otherwise
# require eAmusement plays to unlock? The settings are all in the form of "<key>": <str>. I am not sure what
# the str value should be. They are reproduced here:
