About This File
This is a Japanese Pokemon Ruby save file that I scanned my "Decoration present" E-reader card on to get the Regi Dolls in my save, using official hardware. I discovered that it was possible to use the decoration trader NPC to trade secret base decorations between games to get every secret base decoration in the English games. (Or any language, I just happen to be in North America.)
To get the decoration trader NPC into your game (Without mixing records), your ID needs to end in a 4 or a 5. Alternatively, if you don't have him and you need him. It would be a simple task to create new save files until you get the correct ID, play through the game and mix records to send him to your desired cart.
I've included an insulting diagram on how to get the regi dolls from the Japanese Ruby to the non-JP Emerald with the least amount of record mixing needed, assuming all 3 saves have a decoration trader.
