Engines on Walnut Games

Cube 2

Mon, 01 Jan 0001 00:00:00 +0000

Debian’s cube2 source with our patches: its package.

Technical notes

Debian’s cube2 (0.0.20201229+dfsg-1+ps3.N, packages/cube2) is Sauerbraten’s own engine source (svn at the 2020-12-29 release, minus the bundled enet and the IDE files; the release archive’s src/ differs from it in two files, sound.cpp and stream.cpp, where Debian’s has later upstream fixes). Only Debian’s data, cube2-data, is BananaBread’s. So one engine build with one set of patches runs both BananaBread and Sauerbraten, and Red Eclipse is the same engine family without our patches. The package replaces Debian’s; the release candidate is ps3.354, ps3.442~dev added 0011.

DarkPlaces

Mon, 01 Jan 0001 00:00:00 +0000

Debian buster’s DarkPlaces 0~~20180412~~beta1 (the last with the GL 1.x/2.0 renderpaths) as darkplaces-gl2: its package.

Technical notes

Debian’s DarkPlaces (020180908 and the 2026 git snapshot) has only GL 3.2 core and GLES2 renderpaths, so it can’t run on the RSX. The last snapshot with the GL 1.1/1.3/2.0 renderpaths (RENDERPATH_GL11/GL13/GL20, an SDL2 window, vid_gl20 0 for the combiner path) is 020180412~beta1, Debian buster’s orig tarball (snapshot.debian.org, upstream.mk). Our darkplaces-gl2 (its package, TYPE=upstream, make darkplaces-gl2-deb, 2 MB) builds it with Debian’s 13 patches (link options, no SSE rasterizer off x86, GPU skinning off) and -std=gnu17 (the code uses false/true as enum names; gcc 15 defaults to C23). It installs /usr/games/darkplaces-gl2 beside Debian’s engine and /usr/games/nexuiz-gl2. The one game on it is Nexuiz Classic; built, not yet installed on the PS3.

ioquake3

Mon, 01 Jan 0001 00:00:00 +0000

Debian’s ioquake3 source with our patches: its package.

Technical notes

Our build of Debian’s ioquake3 (1.36+u20260719.58839361+dfsg-1+ps3.N, packages/ioquake3) replaces Debian’s and carries 30 patches (there is no 0017). OpenArena runs on it (its notes), and Quake III Arena with the player’s own data (its notes). Every change sits behind a cvar, so a recipe variant can turn it back to upstream’s behaviour. The PS3 runs ps3.959~dev (0031) since 2026-10-28; the release candidate is ps3.396 (the archived release plan).

ScummVM

Mon, 01 Jan 0001 00:00:00 +0000

Debian’s scummvm, unpatched. It runs each of these games from its original data: the free ones from Debian’s packages, the others from your own copy, which Walnut Games makes into a package. Every game has its own menu entry that starts it directly, fullscreen, with the pad as the mouse; ScummVM’s own launcher stays in the menu for everything else.

Technical notes

Debian’s scummvm, unpatched (2026.4.0+dfsg-1 on the PS3 in the smoke runs of 2026-10-29; 2026.1.0 before). The licence is GPL-3.0-or-later: the sources’ headers since ScummVM 2.7 (Debian’s copyright file still says GPL-2+ for most files). Each game it runs is a GameDB entry of its own (the user, 2026-10-30: “we don’t rate engines, we rate games”); the old scummvm bundle is a draft that keeps ScummVM’s own launcher and the smoke-test recipe.
