How do I open up an unlicensed or Wisdom Tree/Color Dreams cartridge?
You might have noticed if you ever tried to use the method mentioned previously on some unlicensed cartridges, such as those manufactured by Wisdom Tree or Color Dream, that the 3.8 MM bit is too small to remove the screws. A 4.5 MM bit will probably fit, instead, as it is the next most popular screw bit used on cartridge games.
