Game-Specific Tweaks (The Secret Sauce)

For PPSSPP (PSP Emulator):

• Graphics Backend: Vulkan (not OpenGL).
• Rendering Resolution: 3x PSP (1080p).
• Post-Processing Shader: "Natural Colors" (this uses the extra quality shader pipeline).
• Frame Skipping: Off.

For Dolphin (GameCube/Wii):

• Enable "Skip EFB Access from CPU" (massive speedup on Rockchip).
• Shader Compilation Mode: Synchronous (Ubershaders). This prevents stutter.
• Internal Resolution: 2x Native (1080p) is the sweet spot for "extra quality."

For RetroArch (Arcade/PS1/N64):

• Video Driver: Vulkan.
• Run-Ahead Frames: 1 (cuts input lag to nearly zero).
• Hard GPU Sync: On.

Installation Notes

• Prefer over-the-air (OTA) delivery when available—this preserves user settings and performs necessary prechecks.
• For manual installs (factory images or sideload):
  • Backup user data prior to flashing.
  • Follow manufacturer instructions precisely to avoid bricking.
  • Use verified firmware packages signed by the device vendor.
