This is one of our in-house software tools for Famicom, the Famicom Machine Checker Service Diagnostic cartridge. The contains software revision 3.25. We use these cartridges to test various things on the Famiclones and Famicoms in our studio. Originally we weren't going to sell these, but someone had stated that they wanted one so we decided to make a small quantity available for the outside world.

This cartridge comes in a box and contains a variety of hardware tests for your Famicom or Famiclone machine, including color tests and graphics tests.

Please Note:  Although the software contained within each cartridge is the same, cartridge shell may vary from the picture. All cartridges are housed in these "large" shells.
