13 Miss. Code. R. 7-12.18
A licensee shall not alter the operation of approved gaming devices and shall maintain the gaming devices in a suitable condition. Each licensee shall keep a written list of repairs made to gaming devices offered for play to the public that require a replacement of parts that affect the game outcome and shall make the list available for inspection by the Executive Director upon his request. All parts that are integral to the playing of the gaming device, related to the actual game outcome, or associated equipment of the machine must be sold by a licensed manufacturer or distributor. These parts include software, artwork, and other integral components whose installation may be considered a modification of the machine by the MGC. Simple parts that do not constitute a modification of a gaming device or associated equipment (such as simple hardware, bolts, screws, light bulbs, etc.) may be sold by a non-licensed vendor but must be equivalent in performance, specifications and dimensions as the original equipment. The Executive Director reserves the right to make a determination as to whether any seller of gaming device parts and equipment must be licensed by the Commission.
