Star Ocean Anamnesis Nox Data Extraction

Tools Used

• Node.js
• GraphicsMagick
• PVRTexToolCLI.exe (included in repo) but for manual work, you can use PVRTexTool or Mali Texture Compression Tool
• SOADec.exe (included in repo)
• SOAImgEx.exe (included in repo)

Setup

• npm i
• if you want to use image modify features (resize, trim) you will need GraphicsMagick

Get This Module on NPM

You can also find this package on npm as soa-extract: npm i -g soa-extract.

Preparation / Get Files

1. After downloading Star Ocean: Anamnesis, log on, and start the tutorial (you do not need to finish it).
2. Open the Nox file explorer, and navigate to /data/data/com.square_enix.android.android_googleplay.StarOceann\files\download\Image.
3. Copy the etc2 folder to /mnt/shared/OtherShare (which will make it available to your file system in your ~/Nox_Share/Other)

Automatically Ripping Images

It is now possible to automatically rip the files after doing the above steps manually. The CLI is flexible and offers some additional features beyond ripping, as well.

For doing this, you should specify a path to the folder with the .aif files.

CLI Arguments

• --soa-dec-location - the path to SOADec.exe (defaults to ./bin/SOADec.exe)
• --soa-imgex-location - the path to SOAImgEx.exe (defaults to ./bin/SOAImgEx.exe)
• --pvr-textool-location - the path to PVRTexToolCLI.exe (defaults to ./bin/PVRTexToolCLI.exe)
• --output-folder - the path to the desired folder output (defaults to ./output)
• --input-folder - the path to the desired input (defaults to ./input)
• --error-log - the path to the error log file (defaults to ./error.log)
• --filter - filter by files that start with the given text (defaults to '' (no filter));
• --trim - use GraphicsMagick to trim the output images to their borders, usually to resize them to a uniform size
• --resize WxH! - use GraphicsMagick to resize the output images to the specified size, in the WidthxHeight format (for example, 256x256). To force resize in all circumstances, append a ! (for example, 256x256!). You probably will want to use --filter if you're using this.
• --compress - compress the output images using pngquant. It will run default compression. To pass args to pngquant, do --compress="--quality 50-60". A full listing of pngquant args can be found on their website.
• --diff-only - do only a diff and no processing. For this, you still need to specify --output-folder.
• --diff - the path of the folder to compare against to see new / old files
• --diff-log - the path to the diff log file (defaults to ./diff.log)

CLI Examples

• Normal extraction: soa-extract --input-folder=etc2 --output-folder=extract --compress
• Normal extraction w/ diff: soa-extract --input-folder=etc2 --output-folder=extract2 --compress --diff=extract
• Extract item sprites, resize, and compress highly: soa-extract --input-folder=etc2 --output-folder=extract --trim --resize 128x128! --compress="--quality=50-60" --filter=itm_th_
• Diff two folders: soa-extract --diff-only --output-folder=extract2 --diff=extract
• Extract stamps: soa-extract --input-folder=etc2 --output-folder=extract --trim --filter=stp_

Manually Ripping Images

Note: This can be done without setting up or installing Node.js

1. Drag the etc2 folder on top of SOADec.exe - this should produce a lot of files with _unpack in the name, at the end.
   • If desired, you can remove all the other files with find -type f \! -name '*_unpack*' -delete or equivalent
2. Drag any .aif file onto SOAImgEx.exe.
   • This will create a Textures folder with all of the textures for this particular sprite. This can be opened in Mali Texture Compression Tool or PVRTexTool.
   • Doing multiple files at a time will not work because SOAImgEx does not support specific file name output. Ideally, automating this will address this issue as these files can be post-processed.
3. Open or move the image in a different tool and save it as PNG.
4. Repeat ad infintum until you want to gouge your eyes out.
5. Done.
