My kids broke one of their year old Nintendo DS's (the top screen is partially busted) but the rest of it works fine. We replaced it already with a new one, but I was wondering if Gameboy games would work on the broken one since I heard they only use one screen? Would we be able to set it up to work on the bottom screen? I hate to have it go to waste if we could buy some cheaper used Gameboy games that they could play on it. Thanks!
