Features

  • Dual SD & PortMaster Scan: Scans SD1 and SD2 (ROMS/<system>/) plus PortMaster ports (ports/*.sh).
  • Weighted Shake Physics: Hold-and-release shake with power meter. Landing in the sweet spot triggers a “perfect shake” bonus.
  • Smart Weighting: Backlog (×3), favourites (×2), playing (×1.5), beaten (×0.5), with re-pick avoidance.
  • Filters: Filter by system, genre (any/all match), and status, or toggle “Surprise Me” mode.
  • In-App Genre Editor: Modify game genres directly on the result screen without altering read-only gamelist.xml files.
  • CRT Retro Visuals: CRT scanlines, chromatic aberration, neon arcade glow, and synthesized sound effects.
  • Robust Hand-off: Does not launch games directly, preventing core crashes and ensuring 100% stability across all RG35XX models.
