About

Infinite Undiscovery Recompilation is a native Windows x64 recompilation of Infinite Undiscovery, built with ReXGlue / XenonRecomp. It includes a setup wizard that imports game data from a legally obtained copy, supports PAL and NTSC-U media, both discs and two DLC packages, and keeps everything portable beside the executable. The current public release is still under active gameplay validation.

Getting started

Download the latest portable build, extract the ZIP to a writable folder and run the executable. On first launch the Asset Setup Wizard asks for your own game media: Disc 1 is required, while Disc 2 and the A Voucher and B Voucher DLC are optional. It reads supported XDVDFS ISO images or extracted disc folders and reuses a validated setup on later launches.

Known issues & limitations

The real in-game Disc 1 to Disc 2 transition has not been tested, so successful disc switching should not be assumed yet.

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).

You must provide your own legally obtained copy of the game.
The setup system expects default.xex, ud1.bin, and ud2.bin for each disc.
Supported game regions are NTSC-U and PAL.
Disc 1 is required; Disc 2 setup is optional.

Features

The wizard can import the supported A Voucher and B Voucher DLC packages.

How to install

Download the latest portable build from the releases page.
Extract the ZIP to a writable folder and run InfiniteUndiscoveryRecomp.exe.
On first launch, use the Asset Setup Wizard to provide game media and prepare the required files.
The Windows release is portable and does not require an installer.

Summarised from the project's README.

Licensing & legal

The project code is licensed under BSD-3-Clause.

Additional notes

Saves: Saves, shaders, cache, logs and configuration stay local to the portable folder, with PAL and NTSC-U kept separate.
Companion: IU Save Bridge is the official portable save editor companion, supporting Fol, character stats and inventory editing.
