    Overview

    This was my most ambitious build to date — a full-size, 4-player arcade cabinet built from scratch. The goal was to create a party machine that could handle everything from 4-player X-Men and TMNT to competitive Street Fighter sessions.

    The Cabinet

    Built from 3/4" MDF with a black melamine finish. The control panel is wide enough for four sets of controls: each player gets an 8-way Sanwa-style joystick and six 30mm buttons with LED illumination. Player 1 and 2 also have start and coin buttons.

    Dimensions:

  1. Height: — 72" (with marquee)
  2. Width: — 42"
  3. Depth: — 28"
  4. Control panel height: — 36" from floor

    5. Display & Audio

    The 32" LED TV runs at 1080p and is mounted at a slight angle behind tempered glass. Audio is handled by a 2.1 channel setup — two mid-range speakers flanking the marquee and a small subwoofer in the base for that satisfying rumble.

    The LED Marquee

    The marquee runs addressable WS2812B LEDs controlled by an Arduino that syncs colors to the currently loaded game. The marquee art itself is a custom translite printed on backlit film.

    Software Stack

  5. LaunchBox / Big Box — for the frontend — gorgeous visual browsing
  6. RetroArch — handles most emulation (MAME, NES, SNES, Genesis, etc.)
  7. Dolphin — for GameCube/Wii titles
  8. PCSX2 — for PS2 games

    9. The whole system is mapped to a wireless keyboard tucked inside for admin access, but day-to-day everything is controlled with the joysticks and buttons.

    Lessons Learned

  9. Route your wires early — retrofitting cable management is painful
  10. Test the control panel layout — with cardboard first
  11. Don't cheap out on joysticks — you'll feel the difference immediately
  12. Add a PC power button — accessible from outside — reboots happen

    13. Final Result

    This cabinet is the centerpiece of the game room. It gets fired up every weekend, and friends always gravitate toward it. Four-player Simpsons and TMNT never get old.
