I received this Zelda: Link's Awakening DX cartridge for free and when I put it in my gameboy and turn it on, Everything seems fine until I press start on the title screen. After that, my game freezes with a white screen and I don't really know what I can do to fix that. The contacts look really clean. It always freezes at that point. I am thinking that it could be some corrupted save file/battery related problem but it could be as well dirty parts from the board or simply broken ROM. I have no idea though, since I only replaced batteries on GB carts until now. Help would be much appreciated. I looked for this game a lot and getting it fixed would be just amazing.
