I wanted to dig into Metal Gear Rising to hopefuly replace the XBox key legend with the PlayStation one instead. But before doing so I need to extract it first, so after reading the help prompt, I attempted this:

PS E:\CPKTool> .\YACpkTool.exe -X -d "E:\MGR Modding\out" -i "C:\Program Files (x86)\Steam\steamapps\common\METAL GEAR RISING REVENGEANCE\GameData\data000.cpk"
100% extracted...
Status = Complete

Process finished (hopefully) without issues!

But, my output did not end up in E:\MGR Modding\out, but in the CPK's directory instead.

Process finished (hopefully) without issues!
PS E:\CPKTool> dir "C:\Program Files (x86)\Steam\steamapps\common\METAL GEAR RISING REVENGEANCE\GameData"

I don't mind having to stitch those together later, but I feel like this might be a bug, so I wanted to let you know. Also,m the command line used came directly from the README within the YACT subfolder.

Thanks and kind regards,

This happens when I extract a cpk file.

Regenerate the .cpk everytime when you patch many files is a true shit :V
Please, allow 'batch patch'.

Some few games use SJIS (like persona 5) as the file name encoding of the .cpk, this means we can't repack the cpk

There is a cpk file which contains files that have no filenames stored inside the cpk file, and instead, are stored as ID numbers.
As a result, when unpacking the files, they're shown as ID#####.
When repacking into a new cpk file, the files inside it are stored as filenames rather than ID numbers, and as a result, the game has trouble reading files inside the cpk file.

The game in question is Style Savvy: Styling Star (Nintendo 3DS), and the file I used is character_motion.cpk, which contain skeletal animations for the character models.
