The length is not explicitly given, so we have to look at the offset of the next file and take the difference between the two. Other potential cases for errors is in the calculation of file lengths for sub-file types. This seems to work on all tested files (everyone seems to start with the right MAGIC) and was verified by extracting the jpegs shown above, but accurate analysis / testing is impossible without having readers for the various formats contained to ensure that we are actually getting all of the files every time. Of note, for writing Embedded Files to Disk we have to add to their offset by (embeddedFileNumber * 0x8) to produce images without extra padding at the start of each file. Offsets are given relative to their current position in the stream so we tend to have to jump around a bit and do some odd math (where we add the offset of the variable we're reading to the position in memory, etc.) The math on the file extraction is a little. This is why I'm calling it a "partial" extractor - a better understanding (and more code) for the FMDL and various other sub-type sections will have to be documented before completed data can be extracted from the format. It's more of an "optimized package" where data is strewn about the format belonging to various bits of it.

What this means is that A) The BFRES file is not a traditional archive format as the data is not grouped by which file it belongs to. It appears that FSHP and the actual bitmap texture data for models is contained within this block (as well as others?). It appears (at this early point in time) that some sub-types (such as FMDL) actually have references embedded within their files that point to this block which stores data. So where is the missing data you ask?Įnter the section above.

If you run the tool on an archive at this point, you'll end up with not as much content as the file actually holds, yet there are the correct number of files and (to our knowledge) the files are of full length. The BFRES format is organized in the following fashion. BFRES can also contain self-contained files, and sometimes BFRES archives are only composed of these files. The BFRES format is often used as a complex model format that supports shapes, materials, and various types of animations. sarc archives - an extractor is available on this page. Folders for the 12 sub-file types will be generated alongside the. Fairly untested, but seemed to work from what I could see. gtx file containing the actual texture data. More on this in a minute.įTEX files now dump out both their FTEX header, as well as a. There are 11 other sub-types for files and partial extraction of those is supported. The only thing that mostly* works at this point is the extraction of "Embedded Files" (see file spec). bfres files used in Pikmin, Wind Waker, Mario Kart and more.
