Getting Started

This is an example of how to decompress .ch and .th binary files.

Prerequisites

This is an example of how to list things you need to use the software and how to install them.

• phyton
• pwsh

Source (Phyton)

  import zlib
  import sys

  with open(sys.argv[1], 'rb') as f:
      content = f.read()

  decompress = zlib.decompressobj(-zlib.MAX_WBITS)
  inflated = decompress.decompress(content[14:])
  inflated += decompress.flush()

  print(inflated[:-1].decode('utf-8', errors='ignore'))

Usage (Phyton)

    ./decompress.py .\includes\sigawin.ch > sigawin.ch

Source (pwsh)

      param (
          [string]$filePath
      )

      Add-Type -AssemblyName System.IO.Compression

      $bytes = [System.IO.File]::ReadAllBytes($filePath)
      $compressedContent = $bytes[14..($bytes.Length - 1)]
      $stream = New-Object System.IO.MemoryStream
      $stream.Write($compressedContent, 0, $compressedContent.Length)
      $stream.Position = 0

      $decompressor = New-Object System.IO.Compression.DeflateStream($stream, [System.IO.Compression.CompressionMode]::Decompress)
      $reader = New-Object System.IO.StreamReader($decompressor, [System.Text.Encoding]::UTF8)

      $inflated = $reader.ReadToEnd()
      $reader.Close()

      Write-Output ($inflated.Trim())

Usage (pwsh)

     pwsh .\decompress.ps1 -filePath ".\includes\sigawin.ch" > .\sigawin.ch
