The achilles heel of each classic system in Classic Console Discussion Posted July 19, 2013 C64/128: One of the sound channels went out on both of mine... one was a 64 and the other a 128. You could still hear parts of some games but others you had no sound whatsoever. Tapwave Zodiac: I had some issues with the analog joystick on some of mine... the upper left direction doesn't work consistantly. Also the Lithium battery went bad very quickly on some of my units... some hold a charge for hours and hours but others only a few minutes. Gameboy Advance: The screen scratches up very easily and the battery door tabs break off easily. PS2: The door on the tray either gets the tray stuck or falls off altogether... more annoying than anything but both of mine had these issues. Sega Saturn: The controller wires were constantly coming out where they entered the controller. I know this happens with aggressive play on many systems but it seemed like the Saturn was especially vulnerable.
