This is a list of all 425 possible pieces of equipment from the base game that can show up when the Yolanda Bonus Round rule is active.
While this list is not stored in-game, the items listed were determined based on the publicly available Github code that explains some of the internal rules.
Essentially, the code takes all equipment that isn't labeled internally as โskillcardโ, โexcludefromrandomlistsโ, โrobotonlyโ, or โwitchonlyโ. Then with the list returned and shuffled, the code iterates over each shop in the game and checks if it is selling a piece of equipment. If it is, the equipment is replaced with the last element of the equipment list, which is then removed from the list. This continues until all shop equipment has been changed.
