Hmm... 1) Can the pokewalker PID generation restriction be shared out? Would love to be able to generate a Skitty (can't seem to make it right, PID mismatch). 2) PKHEX still can't reroll a PID for pokewalker pokemons?

Sorry to revive this. As I am able to only play on emulators, I must generate Pokewalker-exclusive Pokemons in order to obtain them. I will share my observation for the PID generation for Pokewalker pokemons. As Wichu had noted, the general format of a Pokewalker pokemon is either 0xXX0000YY or 0xXXFFFFYY where, XX is dependant to the TID and SID and YY governs the natures of the pokemon. The calculation for XX is as follow: For PID with format 0xXX0000YY, XX is the upper 8 bits of NOT (TID XOR SID) For PID with format 0xXXFFFFYY*, XX is (the upper 8 bits of NOT (TID XOR SID)) - 1 *not true for this: YY is based on the gender of the pokemon. Do check the gender of generated pokemon at https://www.serebii.net/heartgoldsoulsilver/pokewalker-area.shtml. I had also obtained some .pkm files from HaxAras from below page I had observed that, for pokemons with 0xXXFFFFYY, YY for male pokemons ranges from E8 to FF, while for female, 52 to 6A. However for 0xXX0000YY pokemons, there was insufficient data to deduce a range. It can however be seen that 0xXX0000YY pokemons were usually Pikachus (most likely from Yellow Forest to tell the cartridge of those special Pikachus with special moves. If there is anyone still playing HGSS and real pokemon caught from Pokewalker, it would be appreciated if they are put here.
