FOUNDRYLINUX

Forged for game makers, level designers, and digital artists of every kind — an Ubuntu LTS desktop with the tools of the trade struck into it from the first boot.

$sudo apt install foundry-anvil
№ 01 · The Forge

Struck into the iron.

We package the retro, game-dev, reverse-engineering, and authoring tools Ubuntu doesn’t ship — and push the ones worth shipping upstream into Debian. Built for Ubuntu 26.04. Resigned, rebuilt, and re-tested on every push.

Game Development Kit

World Foundry GDK

Cross-platform engine and 10 CLI authoring tools — cdpack, iffcomp, iffdump, levcomp, lvldump, oaddump, oas2oad, prep, textile, blender-asset-finder-cli. Plus the engine build-deps (build-essential, cmake, libx11-dev, libgl) via worldfoundry-development.

Retro toolkit

Retro-porting and reverse-engineering toolchain. MAME, Ghidra, radare2, binwalk, and the 6502 / Z80 / m68k / 6800-family assemblers and disassemblers — the bench for getting old code running again.
