The Raspberry Pi Arcade Project, Part 1: Introduction

If you’re bothering to read this, I probably don’t need to explain either the Raspberry Pi or emulators (specifically, MAME and Stella), but for the sake of completeness, I will.

Raspberry Pi

The Raspberry Pi is a tiny, inexpensive Linux-based computer that, after years of anticipation, was finally released to the public last year. It’s designed to be versatile and to encourage creative, educational programming and electronics projects.

Emulation Software

Emulators are software programs designed to run on modern computers that emulate the physical hardware of older, simpler video game and computer systems. When combined with ROM files, the programs that ran on those old systems, it is possible to play near-perfect recreations of those classic games on modern equipment.

Of course, while the emulators themselves are (usually) perfectly legal, there is a (charcoal) gray area of legality regarding the distribution and even the possession of these ROM files. Legally, you should only possess ROM files for games you physically own. In the case of home video game consoles, that would be the original cartridges or disks. For arcade games, that would be the actual hardware cabinet with all of its electronic guts… or, at least, the ROM chip from said cabinet that contains the actual game program. (I do actually own an original Asteroids arcade cocktail table, and a very large collection of original game cartridges for the Atari 2600, 5200 and 7800; the Intellivision; the Nintendo Entertainment System [NES] and others. These will be the focus of my efforts with this project.)

There are numerous emulation programs, representing dozens of arcade and home video game systems, and most have been ported to a variety of different modern platforms, including Windows, Mac OS X and Linux. My interest primarily lies with the classic games of the late 1970s and early 1980s; specifically, arcade coin-op games which are emulated by the Multiple Arcade Machine Emulator (MAME) project, and the Atari 2600 which is emulated by the Stella project.

One of the dreams of many aficionados of early arcade games is to own a “MAME cabinet” — a real arcade game cabinet (or modern recreation thereof) with a modern PC and display inside, programmed to work with an arcade-style control panel, and loaded with emulation software.

The Project

I’ve wanted to build a MAME cabinet for years. The biggest hurdle for me has been a willingness to dedicate an expensive (or even semi-expensive) and significantly overpowered PC to use solely as the “brains” of such a cabinet.

I’ve also been interested in the Raspberry Pi ever since I first heard of it. The idea of a credit card-sized Linux computer that could be embedded in a creative electronics project sounded amazing! But possessing a woeful lack of knowledge of the circuit board-level details about electronics, and being equally woefully inept at either soldering or construction, I wasn’t sure what I could really do with it.

But then it hit me… I could build a MAME cabinet! What’s really great about attempting a project like this today is that you don’t really need to solder or build anything. The X-Arcade Tankstick is an (almost) plug-and-play, arcade-quality control panel, and the Xtension Arcade Cabinet is a prefabricated arcade-style cabinet designed to work perfectly with the Tankstick, the PC of your choice, and a 22-inch TV or LCD monitor to create a MAME cabinet that’s still a fun DIY project without requiring the same levels of skill that have previously made this kind of thing unapproachable for me.

The Road Map

I am already well underway with this project, but from the beginning it has been my intention to create a series of blog posts detailing the process, so others who, like me, have an intermediate-or-better level of knowledge of command line Linux; a rudimentary understanding of electronics — at least, which plugs go into which ports; and above all a deep and abiding love of classic ’80s video games, can make this kind of thing happen.

I owe a huge debt of gratitude to Shea Silverman, who is several steps ahead of me in working with and blogging about using the Raspberry Pi for emulation, but whose blog posts come with a tad steeper of a learning curve than what I am hoping to lay out for the readers of these posts. I’ll tell you what I think you need to know to make this stuff work, but for a more in-depth exploration of the details, please check out his blog.

Now then, here’s an outline of the posts I intend to include in this series. (I’ll update this page to make each a clickable link as the posts get published.)

Damn Cords!

I love technology. Someone could call me a technophile and I would accept it as a compliment. But despite my love for all varieties of electronic gadgetry, you may be surprised to discover that I hate cords! In fact, I DESPISE them. They are always getting in the way, they always get tangled together, and if you leave a cord to its own devices (ha ha), it will, I guarantee, find a way to tie itself in a knot.

Not just any ordinary kind of knot, mind you, but a knot of such terrible complexity as to make the Gordian knot unravel itself in fear of a competing knot of such incomprehensible madness.

Solutions are on the way. The technology Apple markets as “AirPort” (and Apple’s name for it is all I care about) promises wireless networking anywhere in the home, and the new “Bluetooth” technology promises to allow us one day soon to connect peripheral devices to a computer merely by placing them in its vicinity.

That’s all well and good, but at the moment I still sit at my desk nervously, wondering if today is the day that the mad cord monster will animate and eat my legs. Today I still have several hundred feet worth of Cat-5 Ethernet cable strung all around my house, tucked into corners as neatly as it will tolerate, aggressively making its presence known in my living room, bedroom and basement.

DO YOU HEAR ME, CORDOSAURUS?! YOUR DAYS ARE NUMBERED!!!
