Lost Odyssey HD Remaster

Status: v0.0.1 test build — playable, with many known bugs · source open (MIT) · bring your own discs Downloads will appear under Releases when the first build is published. See the FAQ.

Lost Odyssey came out on Xbox 360 in 2007 and never left it. This project rebuilds the original game code as a real Windows program — not an emulator — and then gives it what a remaster would.


What you get

  • 720p to 4K, and ultrawide. Pick the output resolution — including Steam Deck (1280×800) and two 21:9 modes — and, separately, how sharp the 3D is rendered.
  • An interface that is always sharp. Menus, HUD and dialogue are drawn at your screen's resolution whatever the 3D costs, and stay exactly where the console put them.
  • DLSS. DLAA, Quality, Balanced, Performance and Ultra Performance for the 3D, on Direct3D 12 and Vulkan.
  • 60 fps.
  • The known crashes are gone. The prison cell, the cutscene after the first boss, the frozen train. None of them happen, with no workarounds.
  • No shader stutter. The port reads your discs and prepares every pipeline the game will need before you play.
  • Sharp text. The game's fonts redrawn from scratch at four times the resolution.
  • HD texture packs. Loaded in the background with no hitches; swap any texture and reload it without leaving the game.
  • No random encounters, at the flick of a switch. Boss and story fights stay.
  • Save anywhere.
  • Turbo up to 8×, on a button.
  • Four discs, no swapping. The game changes disc by itself.
  • Six languages for the game's text, switchable from the menu.
  • PlayStation button prompts, if that is the controller in your hands.
  • All of it in the game's own menu, looking as if it shipped that way.

An interface that stays put

Raise the resolution of a console game and the menus usually drift: a box off its panel, a line pointing at nothing. Not here. And the interface is drawn at the full resolution of your screen even when the 3D is rendered lower.

Ready before you play

On the first launch the port reads your discs and prepares the game's shaders, on a screen made from the game's own fonts and textures.

Preparing shaders

Recommended: let it compile all the shaders (choose all discs in the installer or in Config → Extras). The first run takes a few minutes per disc, but afterwards the game plays without stutter or texture pop-in on every disc. Choosing only the current part works, but you will see hitches whenever you reach a new area for the first time.

Compatible game version and tested hardware

Works with the "USA, Europe" release of Lost Odyssey (Xbox 360), all four discs — the multi-language one: English, Japanese, French, German, Spanish and Italian. The installer checks your discs against known hashes; the Asian edition is not supported yet.

Everything was tuned on one PC (Windows 11, Core i9-10850K, 32 GB RAM, GeForce RTX 3080 10 GB). It has not been tested on anything else, so other hardware may behave differently. Details: Compatibility and test hardware.


Where it stands

PlayableYes — long sessions, saves, achievements, cutscenes
Known crashesFixed
RenderersDirect3D 12 and Vulkan
DLSSBoth renderers
DiscsAll four, from folders, ISO images or Games on Demand
LinuxPlanned, not built yet

The honest part: every crash we know of is fixed, but nobody has played this build from the first minute to the credits yet. The sharp-interface layer is newest on Vulkan, and some 3D scales (×1.25, ×1.75 and other quarter steps) have only been lightly tested. On ultrawide screens videos are still stretched.

The first test build (v0.0.1) is meant for people who want to try it and report crashes: the game reports them itself (it opens a pre-filled GitHub issue). It always needs your own copy of the game.
