Parts of a cab (diagram)

-- Marquee, retainers, light

-- Speakers

-- Control panel (CP), latches, overlay, player buttons, admin buttons (Coin, Start, Exit, Pause, etc.)

-- Kick panel

-- Coin door

-- Sideart (vinyl, stencil)

-- Power supply

-- Game board/MAME computer

-- Wiring harness

-- Smart strip

-- Leveling feet/casters

-- T-molding

What type of build meets my needs? (flowchart?)

-- Start by considering where you want to put/use the cab (measure doorways and available space)

-- Make a list of games you want to play, consider the number of simultaneous players you want to support, and select the computer you want/need to use.

-- That will lead you to what emulators and other software like front ends (MaLa, Hyperspin, etc.) you want/need.

-- From there, you can figure out what kind of controls (Joysticks, player buttons, admin buttons, spinner, trackball, gamepads?) you'll need to work with the games and emulators you want.

-- That leads to chosing the right encoder(s).

-- Browse for artwork/themes/design cues to use in the following steps.

-- Arrange the controls on the control panel. (CP) Cardboard test panel highly encouraged.

-- Select a monitor.

-- Design the rest of the cab around the monitor and CP.

-- Should I build a four player setup?

-- Regular vs. swappable vs. modular panels

-- What controls should I include?

What is JAMMA/JAMMA+?

JAMMA is a wiring standard developed in 1985 by Japan Amusement Machine and Marketing Association, Inc.

It allows you to easily change between JAMMA compatible game boards without re-wiring the cabinet.

The JAMMA standard uses a 56-pin edge connector on the board with inputs and outputs common to most video games.

These include:

- Power inputs (5v and 12v)

- Inputs for two players (each player has a joystick, three action buttons and one start button)

- Analog RGB video output with negative composite sync

- Mono sound output

- Inputs for coin, service, test, and tilt

JAMMA Games that have more than 3 action buttons, more than 2 players, or different control types use the JAMMA+ standard.

Other specialized controls

Yokes, steering wheels, trigger stick, rotary joysticks, light guns, etc.

Mounting options

-- Mounting plate

Encoders

What ports do they use?

USB

PS/2

What type of encoder(s) do I need?

(keyboard, gamepad, optical, combination/hybrid?)

Basic wiring

Quick disconnect sizes

Most microswitches use 0.187" QDs. (4.8 mm)

Some use 0.250" QDs. (6 mm)

Most two tab buttons (Sanwa, Seimitsu, Goldleaf, etc.) and leaf switches use 0.110" QDs. (2.8 mm)

Displays (Arcade CRT/Computer CRT/LCD/LED)

Types of connections

(composite, component, arcade, VGA, DVI, HDMI)

Software

Emulators

(MAME, console emulators, pinball, flash games)

What is an emulator?

A software program that duplicates the hardware, firmware/software, and gameplay of an older game system.

What is a ROM?

For the original games - Read Only Memory chip(s) on the game board/cartridge that holds the program code for a game/game system. For emulators - .ZIP file(s) containing a dump of the game/game system code.

What are the different "flavors" of MAME?

MAME - The command line program that the other variants are based on. MAME32, MAMEUI, or MAMEUIFX - Graphic User Interface (GUI) versions of MAME.

Why won't this ROM work with the newer version of that emulator?

The game may not be fully functional yet. (Encryption issues, driver problems, incomplete ROM dumps, etc.) There may be a more accurate "dump" of that game's ROM used by the newer emulator -- emulator and ROM versions must be compatible. You may also need other driver files or a .CHD (Compressed Hunks of Data) hard drive image.

How can I tell if my ROMs and emulator are compatible?

Use your emulator's "Audit" function to check the ROMs.

Other useful software

(Joy2key, DrVenture's controller remap?, AHK?, mrotate?)

Forum tips for asking questions that get good/faster answers:

- Search first, somebody else has probably encountered this problem before -- don't ask people to retype the same old answers to the same old questions.

- Take your time editing the post so it is specific, clear, and easy to read.

- Whenever possible, include decent pics/screencaps/diagrams.

- Include software/OS versions if applicable.

- Include your location when asking about parts/vendors or electrical wiring. (different countries use different wire colors and/or voltages)
