: Developers use a hex editor (such as HxD) or a dedicated BBK kitchen tool script to unpack the binary structure.

This is where the repacking utility comes in. Just as the initial files were decompressed, they must now be re-compressed using heavy algorithms (like FreeArc, Zlib, or LZMA) to significantly reduce the final file size for distribution or storage. Essential Tools for Repacking
