Yes there is a way to get into glitch city in Gold and Silver. The only way you can move around is with a gameshark. (walk through walls) If you go down far enough, you'll find a black and white girl spinning in place. (???)
If you are brave enough (or foolish enough) you can fight it. But be warned, it is the Gold and Silver missingno and it will crash your game somehow. Also if you want to fight it, you must approach it in a certain way, or else your game will crash.
P.S. If you want to see said ghost go to youtube and type Pokemon:Glitch City Ghost
