The presence flags is a 16 bit parameter of KMP/GOBJ and defines for which number of players an object exists (is visible and active).
First and wrong interpretation
The first interpretation of the flags were derived from /Race/Course/koopa_course.szs/course.0:
<ObjDefine> ... format sepa1_SW user_data 1 Bool 1 format sepa2_SW user_data 1 Bool 1 format sepa4_SW user_data 1 Bool 1 format sepaW1_SW user_data 1 Bool 1 format sepaW2_SW user_data 1 Bool 1 format sepaW4_SW user_data 1 Bool 1 </ObjDefine>
Because a usual presence flag has the value of 0x3f, the first (and wrong) interpretation was:
|First and wrong interpretation|
|0||0x01||Offline single player and time trials.|
|1||0x02||Offline 2 players.|
|2||0x04||Offline 3 or 4 players.|
|3||0x08||Online single player.|
|4||0x10||Online 2 players.|
|5||0x20||Online 3 or 4 players.|
In 2016, Wiimm tested all 16 possible bits of the flags and found a new interpretation: Only the 3 least significant bits are used, all other are ignored:
|0||0x01||Single player (offline and online) and time trials.|
|1||0x02||2 players, offline and online.|
|2||0x04||3 or 4 players, offline.|
|3||0x08||no meaning (ignored)|
|4||0x10||no meaning (ignored)|
|5||0x20||no meaning (ignored)|
It is important to hide objects for 2 players mode only, if they are decorative. Otherwise online players at split-screen will use another track than single players!
In other words: For objects with impact on the gameplay, bit 0 and bit 1 must be equal!
The following table shows typical values. The second column (Same as) reduces the value to the 3 least significant bits:
|0x00||0||Object is always disabled. It's like not defined.||This value is used by custom track authors to disable objects temporarily.|
|0x09||1|| Object is only enabled for single player mode (offline and online), but not for 2 or more players.
Don't use it for objects with impact on the gameplay!
|This value is used by Nintendo to reduce slow motion bug at multiplayer split screen. This value is only used for decorative objects like , but never for objects with impact on the gameplay.|
|0x39||This value is used by many custom track authors to reduce slow motion bug.|
|0x3f||7||Object is always enabled.||Standard value.|
Alternative file *_d.szs
For each track file with the name NAME.szs exists an alternative file with the name NAME_d.szs. This _d file is loaded for 2, 3 and 4 players, but only offline. Theorically it can be a total different track. The idea is to allow easier and less animations to reduce the slow motion bug, but it doesn't help for online racing.
There is a definition for expanding the flags: Extended presence flags
