# GRPort launcher merges Gravity Rush 1 and 2 PC ports for Steam Deck play

> **Key takeaway:** GRPort combines community-made PC recompilation ports of Gravity Rush Remastered and Gravity Rush 2 into a single launcher with Steam Deck-specific performance presets, enabling playable but not flawless handheld Linux gaming.

## Summary
GRPort is a new unified launcher for the community-developed PC ports of Gravity Rush Remastered and Gravity Rush 2, created by qnfn with assistance from Claude AI. The project bridges two PlayStation-exclusive titles to PC through a hybrid approach combining native CPU execution with emulated GPU rendering, positioning it between full recompilation and traditional emulation. The launcher includes built-in achievements, controller icon swapping between PlayStation and Xbox layouts, and two Steam Deck-specific settings presets labeled Performance and Quality.

Testing on Steam Deck shows Gravity Rush Remastered can reach 60 FPS with drops during gravity-shifting traversal, while Gravity Rush 2 maintains a stable 30 FPS but cannot sustain 60 FPS. The Performance preset reduces visual quality without substantially improving framerate, suggesting the Quality preset is preferable for both titles. Users must supply their own legally dumped game files from PS4 copies to use the launcher.

## How GRPort runs on Steam Deck
- **Hybrid execution model:** GRPort uses native CPU execution paired with emulated GPU rendering rather than full hardware emulation or a complete native port, potentially offering efficiency gains over traditional emulation while remaining dependent on GPU translation.
- **Steam Deck integration:** The launcher ships with two dedicated presets for Steam Deck hardware, though testing showed the Performance preset primarily degrades visuals without resolving framerate limitations.
- **Controller input mapping:** PlayStation button icons display by default with an option to switch to Xbox icons, addressing a common compatibility friction point for Steam Deck's built-in controls.
- **File sourcing requirement:** The launcher does not distribute copyrighted game assets; users must dump their own purchased PS4 copies of Gravity Rush Remastered and Gravity Rush 2 to populate the launcher.
- **AI-assisted development:** The project credits Claude AI as a development tool, reflecting a growing pattern of generative AI assistance in open-source and community game preservation tooling.

## Why it matters
GRPort adds to an expanding wave of community-driven recompilation and porting projects that extend the lifespan of console-exclusive titles on Linux and Steam Deck hardware, reducing reliance on full-system emulation. For Steam Deck users, these hybrid ports represent a practical middle path that may eventually outperform emulation as native renderers mature, though current performance tradeoffs show the approach remains a work in progress.
