Vagrant Story Gets Native PC Port With Path Tracing and AI Companion Mod
Square Enix's classic PlayStation RPG Vagrant Story has received an unofficial native PC port featuring path traced lighting, enhanced graphics, and new gameplay mechanics. Developed through the open source rood-boi project, the port brings the 2000 action RPG to Windows and Linux without traditional PlayStation emulation, while an optional companion mod allows Callo Merlose to fight alongside protagonist Ashley Riot.
The rood-boi project, originally developed by noprompt using the rood-reverse decompilation created by ser-pounce, Lil' Sassy, and other contributors, converts the game's original code into native x86 64 executables. Instead of interpreting PlayStation MIPS instructions, the project runs recompiled game logic directly while replacing the console's graphics, audio, and input systems with modern PC implementations.
Its most impressive technical improvement is the modern renderer, which supports Vulkan 1.3 and OpenGL, hardware accelerated ray traced shadows, and path traced indirect lighting with NVIDIA NRD denoising. Additional enhancements include volumetric haze, ambient occlusion, optional widescreen support, and internal rendering resolutions up to 8 times the original. Players can switch between the original PlayStation lighting and more advanced presets, preserving the classic visual style while introducing modern lighting effects.

Beyond graphical improvements, rood-boi introduces optional weapon and shield slots that allow players to swap equipment instantly. This is particularly useful in Vagrant Story, where different weapon types and enemy affinities play an important role in combat. Players can also adjust the camera using the right analog stick and customize environmental lighting through an integrated editor.
The second major gameplay addition comes through Two's a Riot: Tying Up Merlose Ends, an optional companion mod developed by Daemeous. It introduces Callo Merlose as an AI controlled party member, allowing her to follow Ashley, attack enemies, heal, and cast spells independently. She also features customizable equipment, character statistics, and spell selection, while temporarily disappearing during cutscenes to preserve the original narrative presentation.
Daemeous also developed the Windows version and introduced a simplified installation tool that builds the game locally without requiring Windows Subsystem for Linux. Players must provide their own unmodified US PlayStation game image, as neither project distributes copyrighted game assets.
Despite the progress, the native port remains experimental. Exploration, combat, menus, and saving are functional in tested areas, but the ending has not yet been implemented, and the developers have not completed a full playthrough. Some game routines and graphical features also require further testing.
The project follows other preservation initiatives, including Final Fantasy Tactics Advance receiving a native PC port with expanded display and gameplay options. These community efforts demonstrate how recompilation can modernize classic games without replacing their original gameplay foundations.
Vagrant Story's unofficial PC port demonstrates how far community driven game preservation has progressed. Path traced lighting and higher rendering resolutions modernize its presentation, but the quick weapon swapping and companion system could have an even greater impact on the experience.
The addition of Callo Merlose is particularly interesting because it changes the original single character combat structure without requiring an entirely new game engine or rewritten campaign.
However, the unfinished ending remains a significant limitation. Until the full campaign becomes playable and additional compatibility testing is completed, rood-boi should be considered an ambitious technical project rather than a complete replacement for the original PlayStation release.
Would you revisit Vagrant Story with path tracing and an AI companion, or would you prefer Square Enix to release an official remaster?
