Game data

OpenRF needs the contents of the Return Fire CD: the folders ART, SOUND, TITLE and WORLDS, and the file RFIRE.BIN from the root of the CD, next to them (the original game program: OpenRF reads its 3D models, object tables and sound tables from it). The other folders on the disc are not used. It can read them from a folder or straight from a disc image (a raw .bin, of a .bin/.cue pair, or an .iso), with no extraction needed.

Giving OpenRF the CD

• The bundles (Return Fire (gasm).app, openrf.sh, OpenRF.cmd) ask for the CD the first time and remember it: a folder (the disc itself, a mounted image, or a copy) or a .bin / .iso file. A .cue is refused: choose the .bin next to it. See Installing.
• Your own gasm-run: gasm-run openrf.wasm --asset-dir <folder> for a folder, --asset cd=<image> for a .bin or .iso (Running on gasm).
• The browser player asks for the same folder (or image) and keeps a copy in the browser's storage for this site.

To use an image as a folder, mount it. RFIRE.BIN is found regardless of upper/lower case, and is checked against the supported build (431,616 bytes, CRC-32 64c49a1b).

From a disc image

OpenRF reads the ISO 9660 file system of the image itself: plain .iso images (2048-byte sectors) and raw .bin images (2352-byte sectors, MODE1/2352 or MODE2/2352, as in most .bin/.cue dumps). The game runs exactly as from the extracted folder. To extract the files anyway, see Extract the CD image.

Which editions work

OpenRF targets the Windows 95 edition (RFIRE.EXE + RFIRE.BIN, ART/ART.CAR, .RFM maps, .STM movies, SOUND/SCORE.WAV). It was developed with the European release (English, French, German, Spanish, Italian). The 3DO version uses different file formats and is not supported.
