So what you used to be able to do is just ride the Rollercoaster and boom, there's a vinyl, however, there was a patch before the game had it's unpredicted halt that accidentally got rid of the vinyl's normal obtain, SO... here's what you gotta do now, and buckle up because this bullshit is insane.

Well, not "insane" but the couple hoops you do have to go through make running "All Vinyls" or "100%" difficult.

So, what you got to do is find your Dream directory (Program Files (x86)\Steam\steamapps\common\Dream) or alternatively (SteamLibrary\steamapps\common\Dream)

Look in the "Saves" folder and open that, you should see a bunch of files labelled "DREAMVG", this is the file type the game reads, the sizes of the files should be either "17 bytes" or "56 bytes" and the game reads these as "true" or "false" files (17 is false, 56 is true)

Find a file in there called "foundRecord2.dreamvg", this is the coaster's vinyl, delete it. Then find a 56byte file and make a copy of it before renaming it to "foundRecord2.dreamvg" Once you done this, you should be able to just walk up to the Coasters vinyl stand in the portal room and have it register that you have it, HOWEVER, if you did this wrong, then just run around opening/closing doors, finish nightmares, do what you need to in order to find out how to get the vinyl to register.

No, I'm not kidding. You looked at this guide with the intent to obtain the vinyls in this game. This is on you.
