node-pkware

nodejs implementation of StormLib compression/decompression algorhythms

it was the de-facto compression for games from around Y2K, like Arx Fatalis

installation

npm i -g node-pkware

recommended node version: 8.5+

tested in node version 12.7.0

command line interface

implode --input=<filename> --output=<filename> --ascii|--binary --level=1|2|3 - compresses file. if --output is omitted, then output will be placed next to input and names as <filename>.compressed. optionally you can specify an offset from which the compressed data starts with the --offset <byte>, which is useful for mixed files, such as the fts files of Arx Fatalis

explode --input=<filename> --output=<filename> - decompresses file. if --output is omitted, then output will be placed next to input and names as <filename>.decompressed. optionally you can specify an offset from which the compressed data starts with the --offset <byte>, which is useful for mixed files, such as the fts files of Arx Fatalis

example

explode --input=test/files/fast.fts --output=E:/fast.fts.decompressed --offset=1816
