Yggdra Union: We'll Never Fight Alone (PlayStation Portable)/ROM map
The following article is a ROM map for Yggdra Union: We'll Never Fight Alone (PlayStation Portable).
General
This game uses CRIWARE. It is unknown if .afs files are CRIWARE archives.
The main archive file is data0.afs. The full path is PSP_GAME\USRDIR\Data\data0.afs.
All offsets below are absolute (i.e., relative to the start of the file) unless otherwise noted.
AFS Files (main game data archives)
This fork of Puyo Tools will extract the files using the format INDEX-FILENAME (where INDEX is the zero-padded index of the file) when the "Prepend" option is checked. As an alternate method, the Python 3 code on the notes page can be used.
File List
Files in folder PSP_GAME\USRDIR\Data on the UMD or game image. data0 contains most game data, voiceDataEng and voiceDataJpn contain voice clips, 0flist function is unknown and bgmData contains music data.
Subfile Naming Convention
Some files in the data0 archive have the same name and other files have no name at all. Files will be referred to using one of three options:
- A four-digit file number indexed by the order they appear in the archive (example: 0000 for the first file)
- The same four digit number plus a dash plus the file name (example: 0000-ExiData.zlb)
- The same four digit number plus a false extension based on the file type (example: 0354-Br.fct, note that the data0 file name for this file is simply Br)
