This is a set of three of the earliest titles from Hudson's PC Engine library: * Shanghai (released October 30, 1987, launch title) * THE Kung Fu (released November 21, 1987) * Victory Run (released December 28, 1987) The games have been tested and confirmed to work on a PC Engine DUO-R. The back label of Kung Fu has some discoloration and wear. Otherwise, the other items are generally free of noticeable scratches or discoloration. Bundled purchases are welcome. Please feel free to inquire. Thank you.
