This topic provides information about the tool for creating NFC tags in Nintendo's proprietary format (hereafter, NOFT).
Create NOFT by using the tag mastering tool (described later) and
ntag_writer. The keys used for NOFT encryption are different for development hardware and retail units, so tags for development hardware cannot be read from or written to on retail units (or vice versa). The following figure shows the creation flow.
|Flow for creating NFC tags in Nintendo's proprietary format|
To create NOFT, first create the data to use. The data (a
.ntf file) can be created using the tag mastering tool (which runs in Windows). With the tag mastering tool, create the tag data (a
.ntf file) for creating NOFT by specifying the data for the ROM and RAM regions and other necessary information. Using the tag creation tool (
ntag_writer), this data can be written to a NOFT for development hardware. If creating a NOFT for retail units, you must submit the
.ntf file to Nintendo. For more information about how to use this tool and how to submit the NTF file to Nintendo, see the attached materials.
A NOFT can be created by writing an NTF file created with the tag mastering tool to a Type 1 tag distributed by Nintendo. The procedure for using this tool is as follows.
ntag_writerworks with SD cards that are formatted in either FAT or FAT32. Also, only ASCII codes are supported in filenames.
