Lockout Feature
A lockout feature was used to try to stop other manufacturers from copying the player's firmware and making knockoff products, but it was ineffective. Unauthorized knockoffs appeared on the market, and attempting to upgrade the firmware on a knockoff causes the product to reboot to the message "Update Failed! This card is a FAKE!! System Crash!!!" every time it is turned on. Moreover, the locking feature frequently prevents the real GBAMP from booting, especially after quickly turning the power off and on.

Famous quotes containing the word feature:
“When delicate and feeling souls are separated, there is not a feature in the sky, not a movement of the elements, not an aspiration of the breeze, but hints some cause for a lover’s apprehension.”
—Richard Brinsley Sheridan (1751–1816)
