---Player Data Class--
These are stored in an array of 4 items.

Array root address is expected to be $FF5758 (Not 100% confirmed but seems likely based on where this address is referenced in the disasm i.e. (StartGame) ).

sizeof = 76 ($4C) bytes -    This was worked out based on the spacing of the "score" attribute on each player. Each one spaced at exactly 76 bytes between them.
                             Unfortunately does not confirm the start/end address of each instance

PlayerDataInstance:     ; Offsets shown worked out relative to $FF5758 for Player 1. Add $4C bytes for Player 2 etc.
