Just letting you know never go that low on gin unless it's something that is for parts. You could get more if it works. I would offer 30000 for a gin if you had seller wings.
Just so people know this game is official, between the Nintendo logo and the n in pokemon there are 3 digits when you move the game and it also has the square/rectangle in the upper left on the left.
Look for this in all pokemon gba games, squares in the back upper right is a dead give away.
