Hmm...the wave two Tama-Gos have a hole where the screen is so that scratches won't block the display. Try getting a faceplate from a newer style Tama-Go.
Try using toothpaste, or if that doesn't work, try Vaseline. If both don't work, you have to either buy the Wave 2 Tama Go for the plate (woot!) Or, buy some Displex.
May I request this topic be closed? As the solution has been found
