7-1 ROM Size and ROM File Size (Required)

Caution
Ensure that the size of the ROM file is exactly the same as the capacity of the ROM which will be used for production.

Discussion
If the ROM file size is not matched exactly to the production ROM size, the mask ROM cannot be produced and the CRC cannot be calculated. Use makerom from the N64 OS/Library with the following options. 

  -s <romsize(Mbits)>
       Creates a ROM image file with specified size

  -f <filldata(0x00-0xff)>
       Fills the blank area of ROM image with the specified data
