OpenHuey 0.1.17 latest (2026-10-22, fb37842)

OpenHuey 0.1.17: the latest build, from fb37842 on master - replaced on each merge. Its version shows under the debug meters (F2).

You need your own copy of Haunting Ground (USA) for the PlayStation 2: its disc image (.iso). Start openhuey (Linux) or openhuey.exe (Windows); the first time it asks for the disc image and imports it. Mods: mods/ (docs/modding.md). To update: the title's UPDATE, or openhuey --update.

Linux: x86_64, glibc 2.31 or later. Windows: 64-bit.

hga preview 2026-10-14

A first downloadable build of hga, the actor rewrite of Haunting Ground. It's a preview: not all of the game is in yet, and you'll find bugs.

You need your own copy of Haunting Ground (USA) for the PS2, as a disc image (.iso). Nothing from the game is included. On first start hga asks for the .iso and remembers it.

Downloads

• Windows (64-bit): hga-20261014-2777aa4-windows-x64.zip. Unzip it and run hga.exe.
• Linux (x86_64): hga-20261014-2777aa4-linux-x86_64.tar.gz. Unpack it and run ./hga. It needs glibc 2.29 or newer; nothing else needs installing.

hg preview 2026-10-14 (Windows)

A first downloadable build of hg: Haunting Ground's own code, decompiled to C and running natively on Windows. It's a preview: you may run into crashes or parts that don't work yet.

You need your own copy of Haunting Ground (USA) for the PS2, as a disc image (.iso). Nothing from the game is included: hg reads the game's program (SLUS_210.75) and its data from your disc. On first start it asks for the .iso and remembers it.

Download

Windows: hg-20261014-f8f0e94-windows-x86.zip. Unzip it and run hg.exe. It's a 32-bit program, so it runs on 64-bit Windows too.

Controls (keyboard; a gamepad works too)

Key	Action
WASD	Move
Space (hold)	Run
C	Act
Z	Shove / kick
V	Items
E	Flee
I J K L / F	Hewie's commands
Return	Pause / skip
Arrows	Menus
F5 / F9	Quicksave / quickload

Licences

• OpenHuey: GPL-3.0.
• SDL3: zlib licence.
• FFmpeg's libavcodec / libavutil: LGPL 2.1, MPEG-2 decoding only. Their source is linked in licences/.

Built from f8f0e94 (PR #17). Updated: the first upload ran far too fast on Windows and could crash leaving the title with tools/hg_release.sh.
