The Pokémon contestant data structure is a 48-byte structure that determines all information about a contestant in the Generation IV Pokémon Super Contests, such as species, moves, and condition. All numbers are stored in little-endian order.

Notes
Overworld sprite
Only one of each overworld sprite will appear on stage at a time. For example, Alfredo, Collin, and Frank can all appear in Ultra Rank Cool and Tough contests, but because they share the Ace Trainer sprite 
only one of the three will appear in any given contest.
Trainer Class
The Trainer Class almost always lines up with the overworld sprite, but there are exceptions. For example, Frank and Bryant are listed as Veterans but use the Ace Trainer sprite, and Fantina, Johanna, Jasmine, and Casey all share the Worker class. Ultimately this field goes unused, as Coordinators are never shown to have classes in the games.
Pokémon and Coordinator names
Unlike in Generation III, Pokémon and Coordinator names are not stored in the contestant data, but are instead encoded in /msgdata/msg.narc/192 in Diamond and Pearl or /msgdata/msg.narc/205 in Platinum. A contestant's nickname index is always double their contest index, and the Coordinator name index is always the nickname index plus one.
Contest Participation
Contestant rank and categories are controlled by a 8-bit binary number. The first 5 bits control the category, in the order Tough, Smart, Cute, Beauty, Cool (reversed from the usual in-game order). The bit will be 1 if the Pokémon appears in that category and 0 otherwise. Following that there is 1-bit of padding, and then the final 2 bits control which rank the contestant will appear in:
00000-00 Contest categories - rank ------xx 00 (Normal), 01 (Great), 10 (Ultra), or 11 (Master) ----1--- Appears in Cool Contests ---1---- Appears in Beauty Contests --1----- Appears in Cute Contests -1------ Appears in Smart Contests 1------- Appears in Tough Contests
Other flags
All Pokémon in Generation IV have two versions of their sprites, one used for male Pokémon and one for female, which are identical unless the Pokémon has gender differences. This is true even for gender unknown Pokémon like Bronzor and single gender Pokémon like Chansey. In these contests, possibly due to a programming oversight, Johanna's Jumpy uses the 'male' sprite even though all Kangaskhan are female.
00-00000 ------xx 11 if contestant appears only in Practice mode, 00 for all others -----1-- Contestant is Fantina, Johanna, or Jasmine (presumably ensures that exactly one of the three will appear in every Master Rank contest in the post-game) ----1--- Contestant only appears in the post-game ---x---- 0/1 for Male/Female sprite xx------ Unknown flag(s)
