The script is attached to the gist.
You need Python 2.7.14 to run the script.
If you don't know what Python is, or simply don't want to install it, use the EXE version.
SFPac is very old and works only on Sonic Forces. I recommend using HedgeArcPack instead. It has better performance and supports more games.

That's not possible yet. I'm not willing to update SFPac either, sorry.
Hello
I was using SFPac and I wanted to extract a pac file of a mod
But program doesn't work
Is there any other way I can extract it?
I tried HedgeArcPack but it didn't work too
i see switch toolbox can unpack them,but can't repack them (just want to test in the game)
