n64mdiskFormatn64mdisk [config file] n64mdisk -m [master data file name] What This Tool Does It creates the game program�s master data. The master data is used by the developer when submitting an N64 Disk Drive game program to Nintendo after debugging. The data follows a certain fixed format. A disk is created from the master data using a batch file called mwrite for final checking of the game. The n64mdisk tool creates this batch file when it is producing the master data. Note: When presenting the master data, please also provide NCC, the code used for checking the data. Use the calcncc tool to calculate the NCC. The first form of the command (n64mdisk [config file]) creates master data by following the specification in the config file. The second form of the command (n64mdisk -m [master data file name]) creates the mwrite and mwrite.id files from the master data already created. If the master data file name is left off, the master.d64 file is used. This form of the command also checks to make sure the master data file specified (or master.d64) is in fact proper master data. If it isn't, the tool displays the following message and terminates: ******** This is not master data!! **********Also, when the extension of the file is not .d64 the following confirmation is requested: ** This file name does not end with .d64, so it may not be master data OK? (y/n) [y]If you want to use the specified file, input "y" or "Y" or press the Enter key. If you press any other key, the tool terminates without doing anything. More Information When you enter the following command line, the file n64mdisk.cfg (the default config file) is read and its contents used to create the master data file. % n64mdisk [for Partner-N64NW] C> n64mdisk [for Partner-N64PC]Three files are produced at the time the master data is created:
When creating the master data, be sure to use the libleo.a and libultra_rom.a libraries for linking. (The libraries libleo_d.a and libultra_d.a are for debugging.) Please create a disk for final checking using master data linked to libleo.a and libultra_rom.a, and conduct sufficient debugging with this disk before submitting the master. A master production config file can be specified as follows (here named n64mdisk.yes): % n64mdisk n64mdisk.yes [for Partner-N64NW] C> n64mdisk n64mdisk.yes [for Partner-N64PC]Following is an example of such a config file followed by details about each line: USE GWRITE gwrite DISK TYPE AUTO IPL LOAD ADDRESS 0x80000400 RAM START LBA AUTO RAM END LBA AUTO INITIAL CODE NINT GAME VERSION 11 DISK NUMBER 22 DISK USE 0 DESTINATION CODE JAPAN COMPANY CODE 1 FREE AREA 0x123456789abcUSE GWRITE Specifies NO or gwrite. When NO is specified, the ROM INIT. FILE line must also be specified (see below). When gwrite is specified, the master�s ROM region data is created based on the contents of the gwrite file. If the RAM region data is specified in the gwrite file, then RAM region data is also created. Example: USE GWRITE gwrite Example: USE GWRITE NO DISK TYPE Specifies the disk type. Numerical values of 0 to 6 can be specified. For details, see Chapter 11 of the N64 Disk Drive Programmer's Guide. Example: DISK TYPE 0 IPL LOAD ADDRESS Specifies the IPL load address. Refer to Chapter 11 of the N64 Disk Drive Programmer's Guide for the load address. When an address is specified in gwrite with the leowrite -a xxxxxx command, it is given priority. Example: IPL LOAD ADDRESS 0x80000400 IPL LOAD SIZE Specifies the IPL load size. When data is created with gwrite this data is not needed (it is ignored). Refer to Chapter 11 of the N64 Disk Drive Programmer's Guide for information about IPL size. Example: IPL LOAD SIZE 8 ROM INIT. FILE Specifies the image file for ROM region data. This must be specified when no data is created using gwrite. Conversely, when gwrite is used to create data, this cannot be specified. Example: ROM INIT. FILE romimage RAM START LBA Specifies the start LBA for RAM region data. When AUTO is specified, the RAM region start LBA is set according to the disk type specified by DISK TYPE. Specify AUTO even if a RAM region is not being used. Example: RAM START LBA AUTO Example: RAM START LBA 1500 RAM END LBA Specifies the end LBA for RAM region data. When AUTO is specified, the end LBA is automatically set from the RAM region image file size specified by gwrite or RAM INIT. FILE. Example: RAM END LBA AUTO Example: RAM END LBA 2000 RAM INIT. FILE Specifies the image file for RAM region data. Example: RAM INIT. FILE ramimage Note: When there is a clearly specified value for RAM END LBA, the RAM region from the start LBA to the specified end LBA is secured. But at that time, the portions of data where initial values are not specified by gwrite or RAM INIT. FILE are enclosed by 0xFF markers. For details concerning all of the following specifications, see Chapter 6 of the N64 Disk Drive Programmer's Guide. INITAL CODE Specifies the initial code, which must contain at least four ASCII characters. Example: INITIAL CODE NINT GAME VERSION Specifies the game version, which must be at most a two-digit decimal number. Example: GAME VERSION 1 Example: GAME VERSION 99 DISK NUMBER Specifies the disk number, which must be at most a two-digit decimal number. Example: DISK NUMBER 0 Example: DISK NUMBER 99 DISK USE Specifies the disk use code. Example: DISK USE 0 DESTINATION CODE Specifies the destination or the destination code. Example: DESTINATION CODE JAPAN Example: DESTINATION CODE 1 COMPANY CODE Specifies the company code (ASCII two-byte code) of the producer of the game. Example: COMPANY CODE 12 FREE AREA An area to freely write data (at most a 12-digit hexadecimal) Example: FREE AREA 0x123456789abc See Also calcncc
