     * Important data we would like to know for all games:
     * Score
     * Rank (Probably implementation-specific)
     * Note accuracy [List]
     *  Marvelous
     *  Perfect
     *  Great
     *  Good
     *  Bad
     *  OK
     *  Miss
     * Difficulty
     * Song Name / Title
     * Percentage (Can be EX Score, a percentage accuracy or survival percent)
     * Max Combo
     * Other (Not used by the auto detecter, used for storing misc. data.)
     * 
     * Notes about Readers:
     * Love Live
     *  - Does not use: Marvelous, OK
     * Project Diva
     *  - Does not use: Marvelous, OK
     *  - Fail condition is MISSxTAKE
     * DDR
     *  - Does not use: Max Combo (Cannot calculate in combo carryover mode), Bad
     *  - Fail condition is E rank.
     * Pop'n Music
     *  - Does not use: Marvelous, Bad, OK
     *  - Stores number of bars filled in Percentage.
     *  - Fail condition is <17 in the meter (max is 24)
     * Sound Voltex
     *  - Sound Voltex uses the note accuracy list slots as follows: 
     *      Early:
     *          Error - Marvelous
     *          Near - Perfect
     *          Critical - Great
     *          S-Critical - Good
     *          Critical - Bad
     *          Near - OK
     *          Error - Miss
     *  - Sound Voltex stores EX score in Percentage.
     *  - Max Combo is Max Chain
     *  - Sound Voltex will store additional data about accuracy of note types as such:
     *      {"chip":{"scritical":0,"critical":0,"near":0,"error":0},"long":{"scritical":0,"error":0},"vol":{"scritical":0,"error":0},"gauge":<excessive|normal>,"gauge_pct":100}
     *      //Also storing what type of clear gauge was met and the % of the gauge.
     *  - Fail condition is <70% normal gauge.
     * IIDX
     *  - Not going to support right now.
