In Pokemon Gold, Silver, and Crystal versions, all of the items your mom buys with your money that appear in your room, appear in the "My Room" in Pokemon Stadium 2. Once you acquire a console, you'll then have either a NES / Famicom, SNES / Super Famicom, Nintendo 64, or Virtual Boy appear. Depending on which console you have out, the following games will appear on the TV screen:

*NES - Donkey Kong, Kirby's Adventure, Super Mario Bros., or The Legend of Zelda.
*SNES - F-Zero, Kirby Super Star, The Legend of Zelda: A Link to the Past, or Super Mario World.
*Nintendo 64 - The Legend of Zelda: Ocarina of Time, Star Fox 64, Super Mario 64, or Wave Race 64.

No games, however, appear on the TV when the Virtual Boy is out.
