Bezel Guide

Perfect your screen framing for the ultimate immersive experience

What are Bezels?

Retro games were designed for 4:3 or other non-widescreen displays. On modern monitors, this leaves large black bars on the sides. Bezels are high-quality image overlays that frame the game screen with authentic arcade art, console borders, or thematic decorations.

Bezels transform your display from a simple window into a virtual arcade cabinet or a handheld console screen.

Using the Bezel Browser

TruchiEmu includes a powerful Bezel Browser that allows you to discover and download frames without leaving the application.

1. Open the Bezel Selector

From the Game Detail view or the Player overlay, open the Bezel settings.

2. Browse Assets

Explore the available bezels organized by system, or search for specific games.

3. Apply & Download

Select a bezel to apply it instantly. If the asset isn't cached locally, TruchiEmu will download it automatically.

Automatic Mapping

To save you time, TruchiEmu uses a name-based resolution cascade. When you launch a game, the app automatically finds a matching bezel through this priority order:

  • User-Selected Bezel: If you've manually chosen a bezel for this game (unless auto-match is preferred)
  • Exact Game Name Match: Searches local bezel files for an exact match against the game name
  • Cleaned Name Match: Matches with region and revision suffixes removed (e.g., "Super Mario World (USA)" matches "Super Mario World")
  • Fuzzy Match: Normalized comparison against the cached bezel repository manifest
  • No Bezel: If no match is found, the game runs without a bezel overlay

You can disable bezels for any game by selecting "None" as the bezel option. You can also import custom bezel images from your own files — imported bezels take priority in the resolution cascade. Bezels are fetched from a community-maintained GitHub repository; if a bezel isn't cached locally, TruchiEmu downloads it on-demand.

Bezel Fit

Bezel fit is handled automatically. Horizontal bezels assume a 4:3 game area and vertical bezels assume 3:4. The aspect ratio is inferred from the bezel image itself — it is not used as a selection criterion.
