Are Alolan and Galarian forms in BDSP?

Question

I know they're not available to catch, but is there data for them in the code?

Comments

Just because BDSP came out before Legends Arceus doesn't mean that the Hisuian forms won't be added. There was a symbol found in BDSP that shows up on a Pokemon if it originated in Hisui which means the new forms could potentially be added

Oh boy... This escalated a bit...

When I said experience, I meant that I "knew" the answer from personal research (prior to the question's creation).

When SWSH released, I learned online that GAME FREAK leaves unsused assets in the most of the games. Which lead me to believe BDSP was no different. Then after some... "digging", I found that I was correct and BDSP did indeed have all of the unsused items, but no galarian or alolan forms (or any alola/galar pokemon at all). I never datamined or looked through the code, I simply looked through it's item/pokemon indexs with a save editor. :P

Sorry for the 3 month late response, I didn't expect a need to elaborate.

Show me your evidence then

image one is mega stones, image 2 is z crystals, image 3 is dynamax stuff

it should display an option to change it from normal to alola, but it doesn't. Therefore confirming Alolan forms (currently) aren't coded into the game. Same thing happens when trying to make galarian forms.

Ok you can answer with that

No. _{(simple answer, keep reading for details)}

However, items from Alola and Galar such as Z-Crystals or Dynamax Band (also Mega Stones) are coded in. (top image is Mega Stones, middle image is Z-Crystals, bottom image is galar items)

I'm guessing these unused items are leftover from some kind of base game they start with to make newer games from (to make coding easier/faster). I doubt they're intended for a future update.

Also, sorry for the huge images. I tried to shrink them, but since they're so pixelated it only made them impossible to read. :P
