CARTRIDGE FOR GAMING MACHINE AND A GAMING MACHINE USING THE SAME

摘要

A cartridge for a gaming machine is disclosed which includes a case having tapered portions formed at opposite sides thereof and edge portions formed at opposite sides thereof and having a shape different from the tapered portion to prevent insertion of the cartridge into the machine in an inverted condition. A character ROM, a first semiconductor memory storing a program for determining authenticity of the cartridge and a first microcomputer for executing that program are mounted on a printed circuit board accommodated in the case. Contacting portions capable of contacting the tapered parts when the cartridge is inserted are formed at a cartridge inserting portion of a gaming machine main unit. The gaming machine includes a picture processing unit for generating an image signal based on data from the character ROM, a second semiconductor memory which stores the same program for determining authenticity of the cartridge as the program in the first semiconductor memory, and a second microcomputer which is similar to the first microcomputer for executing the program stored in the second semiconductor memory. The second microcomputer determines authenticity of the loaded or inserted cartridge.
