Some programs have special features, enabling the copying of copy-protected disks and Game Doctor disks. If the blank is unable to be successfully written to, the program will display an FDS Error Code. Typically, these programs that use the copiers can copy one entire disk side in a single pass. Some programs require the use of a copier device, which contains more memory than the RAM Adapter. The process must be completed for each disk side.

Once the disk has finished the writing and verification processes (via checksum), the program will display вЂњEndвЂќ or something similar and again revert back to the prompt asking for the source disk to be inserted to begin the copying and writing process anew.

The copy program will then again prompt you to re-insert the blank so it may finish writing the remaining bytes to the disk.

The program will write the data to the disk and then prompt you to insert the source disk once again so it may copy the remaining bytes from the disk into the RAM AdapterвЂ™s memory.

Since the RAM Adapter only has 32KB of program memory and 8KB of character (tile) memory, the copy program will only be able to load about half of the disk into the RAM AdapterвЂ™s memory before prompting you for the target (re: blank) disk you wish to copy onto.

Once loaded, the program will prompt you to insert the source disk you wish to copy.

Insert the disk containing the copy program into the FDS and allow the program to load.

A benefit for using the Dubbing Boy II includes the ability to copy disks with copy protection.ДЄ shortcoming is that, much like copying a cassette tape, data degradation occurs with each successive generation of copies, eventually making copying a disk impossible. To verify the disk is written correctly, flip the switch back to TEST and the disk is loaded into the Famicom via the RAM Adapter. Once synced, flip the switch to COPY, push the blue square button on the upper right, and the disk is вЂњReadвЂќ on the drive connected to the right side and written to the disk in the вЂњWriteвЂќ drive on the left side. The blue potentiometer next to the two green LEDs is used to sync up the drive speeds between the two FDS motors in TEST mode. The switch at the top left says TEST and COPY. The FDS RAM Adapter (already connected to a powered-on Famicom) is connected to the upper left connector. To use the device, the FDS that writes the disk is plugged into left side of the PCB (WRITE) and the drive that the disk is read from is plugged into the right side (READ).

Thanks to Rob Budrick for the magazine advertisement. One such device is the disk-to-disk copying device, Dubbing Boy II (BP-103). In addition to tutorials in вЂњmooksвЂќ like Backup Technique, some companies in Hong Kong produced devices that would enable the connection of two FDS drives for disk-to-disk copying. In this instance, the resulting copy will not be perfect and may not load correctly in different drives since drives are typically adjusted with slight alignment and speed differences. The disk instead retains the header already written onto it. Programs like the NTSC version of Copy Master can copy using a drive that has not been modded, but the program will not re-write the Nintendo-HVC header on the disk. Most require the use of a write-modded FDS so that the entire disk can be rewritten. There are numerous versions of these programs, but for the most part, they all function the same way.
