Bootleg

Something that has been made without the permission of the original copyright owner. Since these items are created illegally for quick profit, they are almost always inferior in some way to the originals. Buyer beware. To reemphasize, these are illegal and grounds for legal action. Playmore (the current holder of all SNK copyrights) has demonstrated its willingness to take to court anyone who violates its copyrights with bootlegs. See Counterfeits.
