CrocUtils

A small collection of utilities for Croc.

The current list is:

  • maptool - A tool for manipulating Croc .MAP files

Soon-to-be-released:

  • cfextract - A tool for extracting CROCFILE.??? files from the PSX releases.
    • Will be released after cleanup

For encoding/decoding of Argonaut ASF files, please see FFmpeg.

maptool

Usage

Usage: maptool decompile <input-file.map> [<output-file.json|->]
       maptool compile <input-file.json|-> <output-file.map>
       maptool convert [--rebase [-]<000-899>] <input-file.map> <output-file.map>
       maptool unwad <input-file.wad> <base-name>

Decompile

Convert any version of a Croc .MAP file into a JSON file for human editing.

Compile

Compile a JSON file into a version 21 Croc .MAP file.

Convert

Convert any version of a Croc .MAP file into version 21, readable by Croc DE.

  • --rebase will offset the door targets by the specified number.

Unwad

Split a PSX MAP%d.wad file into individual .MAP files.

  • Will NOT work with the MP%03d_%02d.WAD files.

Notes

  • Odd padding in PSX maps

    • There was a batch of PSX maps I didn’t extract properly. Either I fopen()'d the file without b and Windows added padding, or the iso extraction too messed up.
    • There were sets of 0x0D 0x0A (or CRLF) randomly in there.
  • Extract the ISOs with https://github.com/cebix/psximager/

  • All 0.12 beta maps convert fine and are either v12_old or v12_old_noambient.

  • The .MAP files SLUS-00593, SLPS-01055, and SLES-00593 are identical. They are either normal, or v12

  • There are differences between the PSX and PC maps. Don’t be alarmed if things look slightly different.
