Bgdata

bgdata (binary game data) files are BYMLs containing lists of GameData flags. They are stored in gamedata.sarc and loaded by GameDataMgr.

bgdata files are most likely machine generated.

Contents

The root node is always a dictionary that contains one of the following keys:

• bool_data
• s32_data
• f32_data
• string_data
• string64_data
• string256_data
• vector2f_data
• vector3f_data
• vector4_data
• bool_array_data
• s32_array_data
• f32_array_data
• string32_array_data
• string64_array_data
• string256_array_data
• vector2f_array_data
• vector3f_array_data
• vector4_array_data

The value for each of these keys is an array of dictionaries:

Key	Type	Description
Category	int	[Optional, present for some flags] Category[check] (only present for boolean flags)
DataName	str	Flag name (unused in release builds; only written for debug purposes)
DeleteRev	int	First game revision where this flag has been deleted[check]. Always -1 in all released versions.
HashValue	int	Flag name CRC32
InitValue	varies	Initial flag value For array types, this is an array that contains a dictionary that in turn contains an array of values, like so: InitValue: - Values: [0, 0, 0, 0, 0, 0, 0] Revival bool flags for objects under the RevivalRandom policy have the position of the object on the main map stored in the upper 7 bits of the initial flag value.
IsEventAssociated	bool	Is associated with an event. If set, GameDataMgr will set the "need gimmick reset" flag (which is ignored in release builds?[check]) after any update. Ignored for non-boolean flags[check]
IsOneTrigger	bool	Whether the flag can only be updated once. More specifically: If true, TriggerParam will not allow updates to the flag if its value is different from the initial value. Also called "change only once" mode ("一度しか変更しない").
IsProgramReadable	bool	Whether the flag can be read by the game
IsProgramWritable	bool	Whether the flag can be written to by the game
IsSave	bool	Whether the flag should be saved[check]
MaxValue	varies	Maximum flag value For array types, this is the maximum value each item in the array can take.
MinValue	varies	Minimum flag value For array types, this is the minimum value each item in the array can take.
ResetType	int	Reset type (see GameDataMgr)

For vector types (vec2, vec3, vec4), a value is stored as an array which further contains an array of values (e.g. [ [-1.0, 0.0] ] for a vec2).

If any key is found, the game will stop parsing the rest of the file.

Note: some of the read/write restrictions (IsOneTrigger, IsProgramReadable, IsProgramWritable) are bypassed whenever the "force" argument in read/write TriggerParam functions is true. Some functions enable or disable permission checks explicitly; others follow GameDataMgr's global configuration, which has two sets of TriggerParam parameters. AIDef:Action/EventFlagONAction always bypasses checks.
