SVI Sector Alpha (Colecovision)

Sector Alpha is a rather rare ColecoVision title that had all of its cartridges shipped with a defect that prevented 10% of the game data from being accessed, which in turn resulted in all ROM dumps being corrupt until the issue was finally discovered in mid-2014. Not only did the game finally get a proper dump as a result, it was also discovered that a simple hack of the cart's PCB will allow the game to function as intended on real hardware.
