PK4: Platinum Debug Pokemon .

Around September 2020, the source code for Platinum was in the wild, and the game could be compiled, with the debug features intact.

Debug start
Debug menu on Title Screen (Select) > Debug Start
The player will start the game in Jubilife City, with 6 starters, being Turtwig, Chimchar, Piplup, Lucario, Croagunk and Carnivine.

Pal Park Entry 1
Debug menu in-game (R + Start) > Tamada > Pokepark Data 1
This first set has Charizard, Squirtle, Wartortle, Caterpie, Sandshrew, and Tentacool.
Given these entries have a Set PID of 0, they cannot be shiny.
Notably, the species encounter are same as the Diamond & Pearl Debug.

Pal Park Entry 2
Debug menu in-game (R + Start) > Tamada > Pokepark Data 2
This second set has Bulbasaur, Beedrill, Clefairy, Sandshrew, Tauros, and Dragonair.
Given these entries have a Set PID of 0, they cannot be shiny.
Notably, the species encounter are same as the Diamond & Pearl Debug.

Box of Slowpoke
Debug menu in-game (R + Start) > Taya > Current Full
This debug option fills the current box to the brim with Slowpoke, all clones.
Since the TID and SID is set to 0, they cannot be shiny.

Box of Slowbro
Debug menu in-game (R + Start) > Taya > Box Full
This box is full of Slowbro. There's 540 different Slowbro. Their PIDs are set, so they can't be shiny.

3 Burmy in party
Debug menu in-game (R + Start) > Tomoya > Test
3 Burmy added to party. Their PIDs are set, so they can't be shiny.
(this option is notably missing)

Roaming Darkrai
As previously reported, a Roaming Darkrai subroutine was found in the final build of the games.
With the debug version of the game, one is capable of encountering it.
Debug menu in-game (R + Start) > Saito > Roaming Pokémon > Location Change > Darkrai

As usual, these files would be illegal and should not be transferred. Use at your own risk.
