Published and community sources

• Community notes on EA's formats — first guesses, each then checked against the data and the exe; no code was copied.

Reference implementations

• FFmpeg's EA demuxer and ffprobe — identified the MAD video, EA-XA ADPCM and the SCxl chunks.
• IJG libjpeg — the front end's JPEG decoder follows its integer IDCT, range limits and upsampling, and is checked against djpeg; the game's own gimme.dll linked it.
• libtiff — the TIFF reader accepts what it accepts.

Tools

Ghidra, ghidra-cli, the Unicorn emulator, wasi-sdk, Binaryen, VitePress; ANGLE and SwiftShader, shipped in the desktop bundles with gasm-run (their notices are in ANGLE-NOTICES.txt). For getting the game off a disc: The Unarchiver and Wine.

Runtime

gasm (MIT): gasm-run, the C SDK, and on this site @emdzej/gasm-host. OpenNFSPU is part of ENCORE, with its sibling reimplementations.
