Name hashing (CRC32)¶

The engine identifies names (WAD files and many other names; there are 120 call sites) with standard CRC-32: reflected polynomial 0xEDB88320, initial value 0xFFFFFFFF, final XOR 0xFFFFFFFF. This gives the same result as zlib.crc32.

Address	Role
`0x143ea0`	Build the 256-entry table (into `.bss` at `0x5d91e0`)
`0x143f68`	`crc32(table, const char*)`
`0x143fd8`	Lowercase a string in place (ctype table at `0x58c531`, `_U` flag)

Callers lowercase the name before hashing, so all hashes are of lowercase strings.

import zlib
def warriors_hash(name: str) -> int:
    return zlib.crc32(name.lower().encode("ascii"))

Confidence: confirmed from code (decompiled table generator and hash loop).

Coney's implementation¶

src/core/name_hash.h: crc32 (of bytes, or of a string as given), lowercaseAscii (A to Z only, so the hash never depends on the host's locale) and nameHash, the CRC-32 of the lowercased string. The CRC table is built at compile time. coney::io::wadPath adds the ./ee_files/ prefix for WAD lookups (WARRIORS.DIR / .WAD). The Python equivalent is name_hash in python/src/coney_tools/wad.py.
