MameDuo Layout Builder

Manual build

Standard layouts and manual section control

Start from scratch, enable only the sections you need, jump between them from the quick menu, and fine-tune size, order, placement, and viewport fit inside the live builder.

H2H Cocktail

Dual playfield layouts

Use the dedicated H2H Cocktail mode when a cabinet needs two gameplay areas in one layout, with its own game-screen section, shared bezel support, and combined fullscreen checking.

Import

Rebuild existing .lay files

Import a working layout, leave it in locked mode, and rebuild imported elements as live editor controls, including extra bezel layers and supported standard-layout image refs.

Second screen

Gameplay on one display, artwork on another

Set Display 1 and Display 2 separately, inspect them one at a time or in Full view, and export split MAME views for \\.\DISPLAY1 and \\.\DISPLAY2, including imported Hi Score layouts with optional turn-flag active-player art.

RetroArch

Overlay and touch-control output

Build merged overlays with layer opacity, scale, rotation, shader options, advanced touch presets, and optional touchscreen zones, then export the matching .cfg plus the composed PNG.

Standard workflow and live preview

• The builder starts with Layout Mode, Display Settings, and a quick-select section list that keeps the main workflow visible.
• Standard mode shows both the gameplay screen area and the outer monitor boundary clearly in the preview.
• Preview chips give instant context for resolution, orientation, mode, enabled sections, and current view bounds.
• Manual layout work is still centered around loading bezel art first, then aligning the gameplay viewport from that frame.

Output editing and export flow

• The output panel is now a first-class workflow area rather than just a download box.
• Full Demo and Full Preview help inspect the real fitted result before export.
• Edit output lets a user adjust exported text and then push those changes back into the live preview state.
• MAME, RetroArch, preview image, clipboard, and download actions stay grouped together in one export area.

Imported layouts and bezel rebuilding

• Imported main bezels and extra bezel layers can now come back as editable live cards in the bezel section.
• That makes it easier to reattach missing art, replace imported layers, and keep the same original structure.
• Imported refs can stay as placeholders until the user uploads the real image files they want to use.
• Lock mode still protects imported geometry until the user deliberately unlocks it for measurement changes.

Secondary display and Hi Score tools

• Secondary Display separates gameplay and artwork across physical monitors while still showing the joined cabinet view.
• Imported score-only layouts can expose a Hi Score block with grouped scale, position, order, and digit-style controls.
• Score Scanner turn-flag imports can now add separate P1 and P2 active-player images that react only while the matching player is active.
• Those active-player images can be static or animated, with folder, frame-count, playback-mode, speed, and frame-delay controls.
• The preview area can also surface extra helper notes such as MAME.INI requirements, animation guidance, and Hi Score export setup.

Turn flag and active-player image workflow

• Import a Score Scanner Hi Score .lay that includes the turn-flag elements.
• Add one or more P1 or P2 active-player image elements, then position each one directly in the preview.
• Choose Static image for a single PNG, or Animated frames for a numbered folder sequence such as anim-seq/anim-seq1.png.
• Playback mode can loop continuously or play once when the player becomes active.
