#### Decoration data in Crystal

Longtime lurker here, first time poster. This stuff has always intrigued me.
Anyway, since I don't have access to Mystery Gift, I'm attempting to simulate it by picking random numbers and adding the items and/or decorations to my game via codes. I'm using the 01??03D0 code and just doing some trial and error. While FF gives them all, it seems that different values pertain to a different set of decorations (e.g. 013303D0 gave me only the Pink Bed and nothing else). Is this correct? Does anyone know how this works exactly? (Stupid question, I'm sure you do know).

EDIT: I mostly figured it out. These values are to be added together to determine which combination you have (e.g. 0166CADA would give you Voltorb, Grimer, Oddish, Magikarp, and Staryu dolls, and not Weedle, Shellder, or Gengar)
The one part I haven't figured out is the big dolls. I'm still experiencing minor graphical glitches with them, which means I've yet to pinpoint the correct value, other than that 017FCCDA gives you Big Onix and Big Lapras without any graphical glitch.
So, the Gameshark code is 01xxC6DA, 01xxC7DA, etc., where adding the hex values together gives a specific combination of decorations.

I had to chance to play around with it a bit this morning.
I already had the Clefairy and Charmander doll from my mother buying them. I had the following results (note that these were added to the dolls I already had):
0100CBDA: Nothing
0101CBDA: Unown doll
0102CBDA: Geodude doll
0103CBDA: Unown doll, Geodude doll
0104CBDA: Machop doll
0105CBDA: Machop doll, Unown doll
0106CBDA: Machop doll, Geodude doll
0107CBDA: Machop doll, Unown doll, Geodude doll
0108CBDA: Tentacool doll
..
010FCBDA: Tentacool, Machop, Geodude, Unown
0110CBDA: Nothing
0111CBDA: Unown
..
0120CBDA: Gold trophy
0121CBDA: Gold trophy, Unown doll
..
0140CBDA: Silver trophy
014BCBDA: Silver trophy, Tentacool doll, Geodude doll, Unown doll
This seems to confirm my suspicions on how this works. I'll continue working on it, but in the meantime, if any of you has done this already, I'd love to hear your results.

This is a bitfield, so each bit is whether or not one or another thing's unlocked, yes.

Yep, it goes through a set of flags to see which you've obtained, like whether you've gotten your starter, beaten Suicune, and stuff like that, in this order.

> C6:
> 10: Feathery
> 20: Pink
> 40: Polkadot
> 80: Pikachu

Note how that's:
0b00010000
0b00100000
0b01000000
0b10000000
So 0b11110000 (0xF0) should give you all four. (The lower four bits seem to be the four Ruins of Alph puzzles.)

> C9:
> 01: Surf Pikachu doll
> 02: Clefairy doll
> 04: Jigglypuff doll
> 08: Bulbasaur doll
> 10: Charmander doll
> 20: Squirtle doll
> 40: Poliwag doll
> 80: Diglett doll

And likewise, 20, 21, 23, and so forth, up to 27 (128, 0x80).
There are 46 of them, ending with the Big Lapras doll, so that should span six bytes, with four bits running over into the one before and two into the one after.

Glitch decorations are also in an unfinished PosterDex on the wiki https://glitchcity.info/wiki/PosterDex Near complete data (however these were gathered empirically; we may not know if any are from RAM) are at https://forums.glitchcity.info/index.php?topic=6202.0 and https://forums.glitchcity.info/index.php?topic=6205.0
