## Executive Summary
Dolphin started out as a GameCube emulator in 2003. In 2008, experimental Wii support was added. And now in 2026, Dolphin enters the realm of arcade emulation with support for the Triforce, a joint Sega, Namco, and Nintendo arcade effort. Want to learn more about the Triforce?

## Architectural & Systems Analysis
From a gaming catalog, platform economics, and Proton runtime perspective, game promotions on Steam directly impact Linux gaming adoption metrics. Key observations:

- **Steam Deck Compatibility & Verification:** Discounted titles should be evaluated against Valve's 'Deck Verified' tiering (anti-cheat compatibility, resolution scaling at 800p, and controller glyph support).
- **Shader Pre-caching Efficiency:** Valve's automated pipeline compiles and distributes Vulkan pipelines ahead of time, mitigating run-time stutter on AMD RDNA architectures without taxing device battery.
- **DRM & Anti-Cheat Friction:** Third-party launcher overhead (e.g. 2K Launcher, EA App) remains the primary friction point; community launch scripts (Proton-GE, Protontricks) provide workarounds to bypass non-standard wrappers.

## Impact on the Open Ecosystem
For Linux and Steam Deck gamers, catalog promotions serve as a benchmark for Linux market share growth. High community demand forces publishers to ensure day-one compatibility with open runtime layers.
