(Gen 7 - SM/USUM) Hex Edit save file to change trainer gender and bedroom decorations?

[TokoyamiTheDark]

Long time no see,

I just lost my Moon save in a stupid way (3DS ran out of batteries), so I thought it could be possible to clone my Sun save file in a Moon one with JKSV and change the Trainer's gender via Hex editing (I use HxD) because PkHex cannot do it on its own. I have found the offsets to change the Trainer's gender, which happens to be at 0x1200. For example, mine is 23 1A 52 7F 1E 00. The ''00'' must be changed to swap Trainer gender.

00 - Boy

01 - Girl

Do note that I can use PkHex to fix some stuff like the clothing since it will be reverted to the default version so it's no big deal.

 

...But now's my problem. When you begin the game, you have your own room. In Sun/Moon, if you have a boy, you'll have a yellow-checked bed and a blue carpet. Girls have a yellow carpet and a green-striped bed. For US/UM, boys have a Poliwhirl carpet and a Pinsir bed; girls get a Jigglypuff carpet and an Eevee bed. Is it possible, that along changing gender, to change your room as well via HEX? I have uploaded 4 dummy save files; 2 for Sun/Moon, and the other 2 for US/UM. For each files, I saved straight after picking up my Starter. The Sun/US saves has a Boy while the Moon/UM saves has a girl. The question is; is it possible to change BOTH the Trainer's Gender AND the player's bedroom layout? I'm also doing search on that, too. It's OK if changing the bedroom's layout can't be done, but that would be a shame...

I think the problem is that it is not documented, and we can’t exactly perform “before and after” comparison to try to see what it’ll be. Short of reading the source or doing trial and error, I’m not sure how would one be able to identify the change.. 

Why don’t you just start a fresh female save, then import the progress from a another save, by importing the Event Flags/Constants block?

I have my save files on my PC. However, I don't see any ''Import/Export Events or Constant block data'' on PkHex's latest version. I know I can edit event constants, but they are merely used for Solgaleo/Lunala/Tapus and the Starter... How can I transfer my 100% Sun save data to my new Moon save so that the story mode is completed despite just starting a new game in Moon? (I might try doing it with US/UM as well)

 

EDIT - Succeded via Hex editing thank to this thread - 

However, I can't go to Poké Pelago or such, as the buttons stays blank... is there any fix to that? Otherwise I got what I wanted. Thank you, theSLAYER!

Hey, just wanted to chime in, I still have to do this process for my best friends Moon savefile as well (I did succeed on doing a gender change on her Y savefile, by transplanting a lot more data than was probably necessary from my own file, but at least it worked that way). So while I haven’t gotten to the Moon (pun intended) savefile yet, I’d like to see how far I can get at figuring out a few more things regarding the currently unidentified savedata blocks.
