@YellowAfterlife I found what 12 of the final 13 bytes are for. They are each a bool for what stats you see overlaid when items in your inventory might generate some.
Equip a Cell Phone, and in the inventory menu, you can click the icon for each readout type to toggle them off.
Dunno if there's a 13th overlay/readout type that a Cell Phone doesn't give, to explain the last byte of the file.
edit: strangely there's a byte amongst these that isn't involved. It's 8, then an odd byte, then 4 more.
edit2:
player files end like so, order doesn't seem to match UI order:
self._is_hotbar_locked = True
self.display_time = True # In-game time of day
self.display_weather = True # In-game weather
self.display_fishing = True # Fishing Power
self.display_position = True # Horizontal position of character (from world centre)
self.display_depth = True # Depth of character
self.display_creatures = True # Creatures nearby
self.display_killcount = True # Kill count of last killed creature
self.display_moon = True # Lunar phase
self.unknown_bytes_6 = b'\x00'
self.display_movementspeed = True # Current speed of character
self.display_treasure = True # Chests nearby
self.display_rares = True # Rare creatures nearby
self.display_dps = True # DPS of current weapon
self.angler_quests_finished = 0
Also, :yoyos: Not sure if there's anything that'll relate to double-yoyo-ing and/or counterweights as yet, haven't managed to work out how to do that.
