QuakeSpasm

What works: Quake's id1/pak0.pak and id1/pak1.pak: its CD or a BIN/CUE image of it (with the CD music), an installed copy (Steam, GOG) or GOG's installer. The 2021 re-release: GOG's Quake Enhanced installer, build 60828 (setup_quake_enhanced_1.0_(60828).exe), or that build installed (with its mission packs and episodes).

• With Walnut Games (the easy way)
• With game-data-packager (a terminal, any Debian system)
• By hand (the files, where they go, their checksums)

1. With Walnut Games

In Walnut Games, open QuakeSpasm: Install, then Add game files... The chooser lists the disc in the drive, mounted discs and USB sticks, GOG and Steam folders, and the ISOs, installers and archives in Downloads and your home folder; you can also pick a file or folder yourself. It checks every file against the checksums below and installs an ordinary package (quake-shareware, quake-registered, quake-rerelease), which Remove data takes away again.

The free shareware needs no copy: choose Download the free shareware in the chooser (it needs the network).

In a terminal, the same with walnut-data (part of Walnut Games):

walnut-data import quakespasm /path/to/your/copy

A source is the disc in the drive (/dev/sr0), an ISO (.iso, .img), a BIN/CUE image (the .cue, or the .bin with its .cue next to it), an Alcohol 120% image (the .mds, or the .mdf), an installer or archive (GOG's setup_*.exe) or a folder (an installed copy, Steam's or GOG's). Images are opened read-only; nothing is copied out of them that the game doesn't need.

walnut-data import -p quake-shareware quakespasm

The free shareware: downloaded whole, no source.

Add-ons, each from a copy that has it (the app shows Also add for every one the source holds):

The CD's music (quake-music): from the disc in the drive game-data-packager rips audio tracks 2 to 11 with cdparanoia; from a BIN/CUE or MDF/MDS image of the CD walnut-data encodes them to Ogg Vorbis itself (oggenc, from vorbis-tools). Ripped audio has no checksum, so the tracks are checked more loosely: the exact names, at most 64.0 MB each, Ogg Vorbis only.

With Walnut's licensed suite as an apt source, the app offers Install from Walnut licensed instead (walnut-data install-repo quakespasm). walnut-data remove quakespasm takes the data away again.

2. With game-data-packager

walnut-data runs game-data-packager, Debian's tool that makes a package out of game data: Walnut's build of it (Debian's 89 with our patches) comes with Walnut Games. Run it yourself to keep the .deb, or to make it on another computer. It writes <package>_<version>_all.deb into the folder after -d (. is the current one), one package per -p:

Then install the file it made, from the same folder:

sudo apt install ./quake-registered_*.deb

• --no-download: only your files are used. Without it game-data-packager may download the official patch files it knows (quake-registered); the commands above leave it out for those. quake-shareware is downloaded whole.
• It reads a folder, an installer or an archive; it doesn't open disc images. Mount an ISO first (open it in the file manager, or udisksctl loop-setup -r -f FILE.iso, then udisksctl mount -b /dev/loopN) and give it the mount point, or let walnut-data do it. BIN/CUE and MDF images: walnut-data only.
• Walnut's patches that concern this game: lha: also ask lhasa for the lower-case names (Quake's CD resource.1); Add quake-rerelease, the 2021 re-release, and GOG's Quake Enhanced installer; quake: keep --package given before the game name; Add the 2021 re-release's add-ons: Armagon, Dissolution, Dimensions of the Past, Dimension of the Machine. Debian's own game-data-packager doesn't have them, so it may refuse some of the copies above, and it can't make quake-rerelease, quake-rerelease-armagon, quake-rerelease-dissolution, quake-rerelease-dopa, quake-rerelease-dimension-of-the-machine at all.

3. By hand

Copy the files to the paths below as root (sudo cp), with the names exactly as written, upper and lower case included: Linux tells them apart. Where a file has several accepted versions, any one of them does. Check a copy with sha256sum FILE (sha1sum or md5sum where the table says so) and compare the sum. Files copied by hand belong to no package: Walnut Games goes by the packages, so it still shows the data as missing, and Remove data leaves them alone.

quake-shareware (shareware)

Into /usr/share/games/quake/id1, 17.8 MB.

game-data-packager also packs 2 documentation files (manuals, licences) into /usr/share/doc/quake-shareware; the game doesn't need them.

quake-registered (full)

Into /usr/share/games/quake/id1, 50.5 MB. It replaces quake-shareware: the two share the folder.

game-data-packager also packs 5 documentation files (manuals, licences) into /usr/share/doc/quake-registered; the game doesn't need them.

quake-rerelease (remaster)

Into /usr/share/games/quake-rerelease, 172.5 MB.

quake-music (music, optional)

Into /usr/share/games/quake/id1/music.

The CD's audio tracks 2 to 11 as Ogg Vorbis files, at most 64.0 MB each (no checksum: every rip differs):

/usr/share/games/quake/id1/music/track02.ogg
/usr/share/games/quake/id1/music/track03.ogg
/usr/share/games/quake/id1/music/track04.ogg
/usr/share/games/quake/id1/music/track05.ogg
/usr/share/games/quake/id1/music/track06.ogg
