This page is related to MKWii Network Protocol and describes the record type SELECT in GNU C notation.
During phase 1 (SEL/PREPARE), the Wiis synchronize their clocks using "time_sender" and "time_receiver" so the race starts at the same time on all Wiis.
Original game
This is the SELECT packet used by the original game:
typedef struct udp_select_t
{
/*00*/ u64 time_sender; // NULL or time of sender (milliseconds since 2000-01-01, based on real time clock)
/*08*/ u64 time_receiver; // NULL or assumed time of the receiver, based on the last received time
/*10*/ u16 rank_pl1; // rank of previous race == start position of next race (Player 1)
/*12*/ u16 sum_pts_pl1; // accumulated event points (Player 1)
/*14*/ u8 driver_pl1; // Driver of Player 1
/*15*/ u8 vehicle_pl1; // Vehicle of Player 1
/*16*/ u8 user_track_pl1; // 0x00-0x1f:course ID, 0x20-0x29:battle course ID, 0x43:none, 0xff:random
/*17*/ u8 ranking_pl1; // star ranking of player 1
/*18*/ u16 rank_pl2; // rank of previous race (Player 2. 0x00 if there is only one player)
/*1a*/ u16 sum_pts_pl2; // accumulated event points (Player 2. 0x00 if there is only one player)
/*1c*/ u8 driver_pl2; // Driver of Player 2 (0x30 when only one player)
/*1d*/ u8 vehicle_pl2; // Vehicle of Player 2 (0x24 when only one player)
/*1e*/ u8 user_track_pl2; // 0x00-0x1f:course ID, 0x20-0x29:battle course ID, 0x43:none, 0xff:random (one player: 0x43; two players: same as user_track_pl1)
/*1f*/ u8 ranking_pl2; // star ranking of player 2
/*20*/ u32 select_id; // a unique id, changed for every race/battle to a random value.
/*24*/ u8 battle_type; // Value indicating if COIN or BOSS-Battle (in SEL1) (0x00: UNKNOWN or COIN, 0x80: BOSS)
/*25*/ u24 team; // 2 bits for each client slot. Bit is set for red team.
/*28*/ u8 client_slot[12]; // relation race_slot(index) : client slot (0xff=none)
/*34*/ u8 sel_track; // game: selected track: 0xff:none
/*35*/ u8 sel_phase; // selection phase: 0:prepare, 1:wait, 2:lottery
/*36*/ u8 sel_client; // client index: who has selected the track (0xff: none)
/*37*/ u8 sel_engine; // 0:none, 1:100cc, 2:150cc 3:mirror (WW and 1st race of GP)
/*38*/

LE-CODE
This is the modified SELECT packet used by the LE-CODE to allow for up to 0x7ffe = 32766 slots online:
typedef struct udp_select_t
{
/*00*/ u64 time_sender; // NULL or time of sender (milliseconds since 2000-01-01, based on real time clock)
/*08*/ u64 time_receiver; // NULL or assumed time of the receiver, based on the last received time
/*10*/ u16 user_track_pl1; // 0x0043: not voted yet, 0x0000-0x7fff: VS/BT tracks, 0xffff: Random
/*12*/ u16 sum_pts_pl1; // accumulated event points (Player 1)
/*14*/ u8 driver_pl1; // Driver of Player 1
/*15*/ u8 vehicle_pl1; // Vehicle of Player 1
/*16*/ u8 rank_pl1; // rank of previous race == start position of next race (Player 1)
/*17*/ u8 ranking_pl1; // star ranking of player 1
/*18*/ u16 user_track_pl2; // 0x0043: not voted yet, 0x0000-0x7fff: VS/BT tracks, 0xffff: Random. 0x0043 if there is only one player
/*1a*/ u16 sum_pts_pl2; // accumulated event points (Player 2. 0x00 if there is only one player)
/*1c*/ u8 driver_pl2; // Driver of Player 2 (0x30 when only one player)
/*1d*/ u8 vehicle_pl2; // Vehicle of Player 2 (0x24 when only one player)
/*1e*/ u8 rank_pl2; // rank of previous race == start position of next race (Player 2). 0 if there is only one player
/*1f*/ u8 ranking_pl2; // star ranking of player 2
/*20*/ u16 select_id; // a unique id, changed for every race/battle to a random value.
/*22*/ u16 ram_junk; // random data from RAM that just happened to be laying around
/*24*/ u8 battle_type; // Value indicating if COIN or BOSS-Battle (in SEL1) (0x00: UNKNOWN or COIN, 0x80: BOSS)
/*25*/ u24 team; // 2 bits for each client slot. Bit is set for red team.
/*28*/ u8 client_slot[12]; // relation race_slot(index) : client slot (0xff=none)
/*34*/ u16 sel_track; // game: selected track: 0xffff: none
/*36*/ u8 sel_client; // client index: who has selected the track (0xff: none)
/*37*/ u8 sel_engine_phase; // highest four bits: selection phase: 0:prepare, 1:wait, 2:lottery
