Tools for Repacking

[wrathma]

wem(un)pak

This is a more feature packed version of Masquerade's WemTool that i made few months ago to compress wem files from Silent Hill f. As it was made with golang, the binary sizes are huge. I didnt want to port this entire thing ito c, so today i added a feature to generate a batch script to decompress the files. Then you can run the batch script in parallel with prl or Mparallel. It follows same file naming standards as original WemTool. So you can use wempack to decompress WemTool compressed data. Attachments include source code.

• Separate compressor and decompressor.
• Ability to compare input and compressed sizes.
• Works recursively.
• Ability to specify compressor for hdiffz.
• Ability to generate a batch script to decompress.
• Better error handling and processing structure:
• compressor : ww2ogg > oggre_enc > oggre_dec > hdiffz
• decompressor : oggre_dec > hdiffz
• If any of the steps fails, the tool skips that file automatically. Temporary files are deleted in every step of processing, WemTool processes all files and then removes temps at the very end, leaving a huge mess and sometimes filling up the disk.
