    COMPLETE BUILD: ~$200–$250

    All components below, excluding enclosure and tools

    CORE COMPONENTS

    Raspberry Pi 4B (4GB)

    $55–$80

    The brains of the build. Runs RetroPie, handles everything through PS1 smoothly.

    Verdict: Essential. Don't go lower than 4GB RAM.

    Buy

    MakerFocus UPS HAT

    $20–$30

    Battery power via GPIO header. USB-C charging, 2× 18650 cells, regulated 5V output.

    Verdict: Best single upgrade. Makes the cabinet portable.

    Buy

    18650 Batteries (Samsung 30Q)

    $8–$15

    High-capacity rechargeable cells for the UPS HAT. Always use matched pairs.

    Verdict: Don't cheap out — name brand cells last 3× longer.

    Buy

    32GB MicroSD Card (A2)

    $8–$15

    Holds the OS and ROMs. A2-rated for faster random reads during emulation.

    Verdict: A2 rating genuinely improves load times.

    Buy

    USB-C Power Supply (5V/3A)

    $8–$15

    Charges the UPS HAT. Any quality phone charger works.

    Verdict: Boring but necessary. Get one with a long cable.

    Buy

    DISPLAY

    3.5" 640×480 IPS LCD

    $20–$35

    Sharp IPS panel with driver board. Connects via HDMI, powered from GPIO.

    Verdict: IPS is non-negotiable. TN panels look terrible at angles.

    Buy

    Micro-HDMI Cable/Adapter

    $5–$10

    Connects Pi 4 to the LCD driver board. Short cable preferred over dongle.

    Verdict: Get a short flexible cable — dongles add bulk.

    Buy

    CONTROLS

    6×6×5mm Tactile Switches

    $3–$5

    Tiny but clicky. Perfect for 1/6 scale action buttons. Pack of 100.

    LED Coin Buttons (7×7×7mm)

    $3–$5

    4-pin tactile switch with built-in blue LED. For coin/start buttons.

    Verdict: The blue glow adds character. Wire LED separately.

    Buy

    DPDT Latching Power Switch

    $3–$5

    7×7mm latching push button. Clean on/off without software menus.

    Verdict: Latching type is key — momentary won't work here.

    Buy

    28–30 AWG Silicone Wire

    $8–$12

    Flexible stranded wire in multiple colors. Essential for tight routing.
