Pokemon Gold Version (Game Boy Color, 2000)

I love pokemon gold and silver versions, I remember when I was in seventh grade I couldn't wait for the game to come out and I beg my mom to get it for me. I got both games brand new, I loan my pokemon gold to a friend but he lost it. I was upset but i got over it. I look through my red,blue,yellow,silver and crystal versions and I caught every pokemon in each game, but I realized that I was missing gold, so I went to a Gamestop and I bought a used gold version, it turned out that the game erases every time you put it on. So I sold that one back but didn't get much out for it. I look through ebay and I found an item that said new pokemon gold version sealed in a box and I took a chance with my money and bought it and so far it was worth it.
