Sabre unPacker is a tool used to decompile .s3dpak files to be able to extract content.
Sabre unPacker is a program that will extract the contents from a s3dpak file (and with future updates hopefully other sabre files) Icon is still being developed.
Currently it's in beta version. If there are any features you want to see added, just put them in the comments.
Select the files you wish to extract, and select a location for them to go.
profit.
I hope this is a good step towards helping research the engine a bit more.
future plans are to repack, and add the ability to read ipak
