Infinite Undiscovery Recomp v1.0.0-rc1

on GitHub

Pre-release / Release Candidate. This is the first public Release Candidate of
Infinite Undiscovery Recomp. It is not the final release, may contain bugs, and
feedback is very welcome.

Infinite Undiscovery Recomp is a native Windows x64 recompilation of Infinite
Undiscovery (Xbox 360), built with ReXGlue. It contains no game files. You
must provide your own legally obtained copy of the game.

Highlights

• Content profiles: USA, USA-UNDUB (Japanese voices), EUROPE, JAPAN, ASIA —
  each kept isolated with its own assets, saves, shaders, cache, logs and config.
• Legacy migration: existing NTSC-U and PAL folders are migrated
  automatically on first launch (NTSC-U -> USA, PAL -> EUROPE).
• Content Profile Manager: browse, select, set active, install/auto-detect and
  manage multiple profiles.
• Asset Setup Wizard: integrated native setup with English / Spanish UI,
  auto-detect from a folder, ISO image or extracted-folder input.
• In-game Game Menu (F5) with a Session / System diagnostics panel.
• Recovery tools: Save Anywhere (F6), Safe Step Forward (F8), Undo Debug Move (F9).
• Multi-disc support: Disc 1 / Disc 2 detection, isolated disc assets, runtime
  Disc 2 handling and a successfully validated real in-game Disc 1 -> Disc 2 transition.
• PSO prewarm at startup and optional PSO telemetry.
• Official save companion: IU Save Bridge v2.3.0, the official portable save
  editor companion (separate project) — https://github.com/doc-haz/iu-save-bridge

Runtime / dependencies

• ReXGlue v0.10.0, pinned to the auditable source checkout
  (rexglue-sdk-v0.10.0-git, commit f5337cdc947ff6d4c4196737e2c807a48f2a1fc2).
  rexruntime.dll and rexgpu-xenos.dll are rebuilt from that source; the old
  precompiled-SDK DLLs are rejected by a build-time hash guard.
• Requires the Microsoft Visual C++ Redistributable 2015-2022 (x64):
  MSVCP140.dll, MSVCP140_ATOMIC_WAIT.dll, VCRUNTIME140.dll,
  VCRUNTIME140_1.dll. These Microsoft DLLs are not bundled.
• A Direct3D 12 capable GPU (the runtime uses ReXGlue's xenos GPU plugin on D3D12).

Official Save Companion

IU Save Bridge v2.3.0 is the official portable save editor companion for
Infinite Undiscovery Recomp.

It follows the same five-profile model used by the recomp:

• USA
• USA-UNDUB
• EUROPE
• JAPAN
• ASIA

Legacy compatibility is preserved:

• NTSC-U -> USA
• PAL -> EUROPE

Repository:

Features include:

• direct save editing
• Fol editing
• character stat editing
• inventory editing
• automatic save discovery
• Xbox 360 / STFS save import
• profile-aware save discovery

Real retail save validation has been performed with USA and legacy NTSC-U saves.

USA-UNDUB, EUROPE, JAPAN and ASIA save handling is currently validated through
the shared save format and synthetic fixtures.

Validation

The current RC has been validated with:

• clean Release build from a fresh build directory
• startup and window creation
• ReXGlue v0.10.0 runtime loading
• Direct3D 12 device creation
• shader translation and graphics pipeline creation
• profile loading
• save loading
• real gameplay rendering
• Disc 1 media detection and import
• Disc 2 media detection and import
• real in-game Disc 1 -> Disc 2 transition, successfully tested multiple times
• DLC validation and loading
• clean shutdown

The real in-game Disc 1 -> Disc 2 transition is considered validated.

Full-game completion and later Disc 2 progression remain under active validation.

Microsoft Defender reported 0 detections on the final public artifacts,
including the EXE, both runtime DLLs, release staging folder and both release ZIPs.
