Technical notes

Wolfenstein 3D source port by Braden Obrzut. Plays Wolf3D (wl6/wl1), Spear of Destiny (sod/sdm), Super 3D Noah's Ark (n3d), and community pk3 mods. Blake Stone and Rise of the Triad support flagged as Preview in upstream.

Requires ecwolf.pk3 — engine data package built from wadsrc/static/. Contains IWADINFO (game detection rules), palettes, sprites, map configs, DECORATE actor definitions, MAPINFO, SNDINFO, fonts, and localization strings. Without this file: "Could not open ecwolf.pk3!" fatal error.

Libretro no longer reads ecwolf.pk3 from disk: it is compiled into the core as a byte array and opened through a MemoryReader, with a fatal error naming it "embedded" when that fails. The system directory is still passed to SelectGame, but for the game data search, not for the engine package. ref: src/libretro/ecwolf_pk3_data.c, src/wl_iwad.cpp:664-672, src/libretro/libretro.cpp:1009-1011

Standalone: ecwolf.pk3 searched in progdir (binary directory). ref: src/libretro/wl_main.cpp:1271 (progdir passed to SelectGame) Also: INSTALL_PREFIX/share/ecwolf/ on Linux (src/wl_iwad.cpp:648)

Game data files (vswap, gamemaps, vgagraph, audiot) loaded from content directory, not system directory. Auto-detects game variant by scanning lump contents against IWADINFO MustContain rules.

Libretro fork based on ECWolf 1.3.99999-dev (forked 2020-02-23). Upstream head at 1.5.0pre with broader game support.
