Do I need the original game files to run Lost Odyssey Recompilation?

Yes. The project does not include the original game's assets, so you need your own copy.

Lost Odyssey Recompilation

RecompilationActive

The original game's compiled code translated into a native program for a new platform, usually a PC port.

About

Lost Odyssey Recomp is an experimental native PC port of Lost Odyssey for Xbox 360. The README says it is in early testing: opening areas and selected scenes have been tested, but a complete playthrough has not, and rendering and stability issues remain. Packages are listed for Windows x64 and Linux x64, with macOS arm64 and Android arm64 marked experimental.

Getting started

You supply your own game data: an extracted game folder, default.xex, an ISO or GOD data. The importer opens when no game is found; Disc 1 is required to start, and the other discs and DLC can be imported later in Settings. On first start the game offers to download precompiled shaders, or compiles them once on your PC.

Known issues & limitations

The port is in early testing: only opening areas and selected scenes have been tested, not a complete playthrough, and rendering and stability issues remain.
Full playthroughs, later discs, Linux and macOS hardware, fullscreen, and mixed-DPI setups still need testing.
The experimental macOS app is not notarized, and only one Mac has run the game so far.
Save Anywhere saves made while the party is split can lose RB character switching; keep a normal save too.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Xbox 360 version).

Features

The project supports texture, menu, and font replacements, as well as PlayStation button prompts.
Controllers, keyboard, rumble, and Android touch controls are supported.
A debug menu offers render captures, Save Anywhere, No Random Encounters, teleport, fast-forward, and cheats.
The game offers menus in English, Japanese, Korean, Traditional Chinese, and Simplified Chinese; game languages depend on the edition.

How to install

Import game data through the importer using Files or Folder to select an extracted folder, default.xex, ISO, or GOD data.

Controls

F1 opens the debug menu; on a controller, use LB+RB, or L1+R1 on PlayStation layouts.
For Ring actions, use the controller's right trigger or the R key.
The debug menu uses keyboard or controller, not the mouse.
