This is the file format used in [[TRON]]. The file can contain text (with its own character encoding), graphics (both raster and vector graphics), and other things, including specification of page layout, and application specific data (with a 48-bit application ID number).

Most of the available information about this file format is Japanese, and the known files also are Japanese.

A TRON archive file usually has extension <code>.bpk</code>. (Should there be a separate article?) The known files of this type uses a FIG segment, a DFUSEN segment with application ID <code>8000.c003.8000</code>, and then a FIGEND segment. (The data of DFUSEN segment seems to be compressed data, but I don't know what compression it uses.)

==Identification==
A small-endian TRON file will start by: {{magic|e0 ff 06 00 00 00 02 00 21 01}} (or at least the first two bytes will be). (This is a INFO segment; the first segment is always a INFO segment.)

After the INFO segment, usually the rest of the file will either be enclosed by a TEXT and TEXTEND segment or a FIG and FIGEND segment.
