G:Final Fantasy 4 (Japanese Version)

C:The Gunslinger Code|00CF-A469|aerostar13@aol.com|These codes are for the JAPANESE version of FF4, "hard type".  I used the ROM address conversion technique to compare the Japanese and American games and adjusted some of the codes to the new memory addresses.

T:Can Buy Any Items Codes
