5/7/2012 PAL version available, tell your European friends!
PAL & NTSC versions of Star Castle cartridges are now available! Don't worry if you've already ordered a cartridge, when the campaign is over I'll be sending everyone confirmation emails asking for shipping information, names for the manual, PAL/NTSC preference, etc.
I can not modify the rewards because people have already pledged, please ignore the "NTSC only" text.
In 1981 a young Howard Scott Warshaw, left his first programming job at HP for a more interesting job at Atari. His first assignment was to create an Atari 2600 conversion of the vector coin op game Star Castle. In this game, you pilot a ship around the screen trying to defeat the Star Castle by shooting the Energy Cannon, but first you must blow holes its rotating shields while avoiding the ever pursuing Space Mines and beware, the Energy Cannon will blast back through openings in the shields! After evaluating the arcade game and the console hardware he came to the conclusion "that a decent version couldn’t be done" (interview link), and "that this conversion would suck on the VCS system" (interview link). So he reorganized the core game-play elements into a new game designed specifically for the 2600. That game became Yars' Revenge, the most successful original Atari game ever for the Atari 2600 (play it free on Atari's site here!).
I love video game history, and I love this story in particular, but when I read about it in MIT Press's excellent historical Atari 2600 book "Racing the Beam" in 2008 something stuck with me. I thought surely Star Castle could be done, there must be some way, so I set out to try.
Every engineer, no matter the discipline, is drawn to some particular project. This project becomes the nagging pull that draws an engineer ever-onward. For me, that project was Star Castle. I'm an Atari fanatic; I always have been. I'm also a Star Castle fan. I used to pump quarters into that machine at the local bowling alley every day after school. It's no surprise that I ended up becoming a video game developer. My first job in the game industry was also at Atari where I worked on the 2600, though six years after Yars' Revenge was made.
I dug deep into my crawl space and excavated the documentation and samples I had from when I worked for Atari and cobbled together a 2600 development environment.
The Atari 2600 only has 128 bytes of RAM (variables start at the bottom, the stack comes down from the top, and you pray they never meet), and you have to build the display line by line using a handful of hardware registers while the electron beam is scanning the TV screen. You have to use a lot of "tricks" to get more graphics and colors on the screen and you still need to handle input, sound, and make a playable game, all in a little less than 8192 (8K) bytes of ROM in my case. To be fair, Yars' Revenge used a 4096 (4K) byte cartridge which is a marvelous feat, but another similar game, Asteroids was released on an 8K cartridge the same year. My goal was to make a Star Castle game that could have been made in 1981 which meant I had to stay within 8K.
I started with a lot of ego and confidence that was soon dashed, the first couple of attempts were miserable humbling failures. It quickly became clear that if possible it was going to be a terrific challenge. I hit timing and space limitations one after another until, several months later, I was able to draw rotating shields, after that, the enemy cannon, then the space mines, and the players ship, the players bullets, and the cannons dreaded energy blast, and then AI, collision, sound... and by early 2010 I had done it. I had created a faithful reproduction of the game experience on the Atari 2600 in 8K.
I was so proud, I showed the game at the Video Game Summit, a local video game conference where it was received with surprising enthusiasm so I kept working on the project. By 2011 I had made improvements to the AI, collision, level progression, and designed my own cartridge. It's all original from the circuit board to the programmable logic chip to the lights inside the cartridge that actually flash with the gameplay - something I NEVER would have expected to find in an Atari cartridge as a kid.
Now that it had lights, a traditional black case would not do, so I designed and machined my own custom clear Lexan case (on a CNC machine that I designed and built myself but that's another story)
and made a reproduction Atari game box.
The response after showing the game in 2011 was overwhelming.
This is one of the coolest things I have ever done. It's a technical accomplishment and it's really really fun! Right now there is only this one cartridge that I made by hand.
It took nearly three years of software, electronic, and hardware engineering to get this project this far. To make cartridges I'll need to have boards made and programmed, molds made, cartridge shells cast, manuals, boxes, labels and CD's made, but I'm ready. If successful, this Kickstarter will allow me to make Star Castle 2600 available to the many people who have expressed interest in the game.
If you are a collector you can get a cartridge and play it the way it was meant to be played: on an Atari, with a joystick, in front of a TV (preferably an old one).
If you're a casual player you can play it on just about any PC. Many people prefer playing Atari 2600 the games on the Stella emulator because it's easy, convenient, the emulation is indistinguishable from the real thing, and the picture and sound are perfectly crystal clear.
If you are a developer or just interested in programming, the game comes with all the source code and art on the CD, everything you need to build your own copy of the game (you have to download the free compiler, but the link is on the CD). You can look it over if you are just curious, or you can modify it and make it your own. The game comes with Stella which includes a full Atari 2600 graphical debugger that allows you to step through each instruction, line, or frame of the game and graphically shows all of the registers in real-time.
This may be the only chance you have to get Star Castle 2600, after this Kickstarter campaign there are no plans to produce or make available any additional cartridges, CD's, or materials.
So, you may be wondering why anyone would bother to make a version of a 30 year old vector arcade game on an arcane 33 year old platform? I was inspired by one of the greatest and most influential game programmers of all time to make something that he said was impossible. I don't consider this a game development project, rather an alternative history art piece*, a demonstration that it could indeed be done.
* I have nothing but the greatest respect and admiration for all of Howard Scott Warshaw's work. I in no way mean to discredit or demean his magnificent ground breaking accomplishments in Yars' Revenge or any of his other titles. Also, if you really want a great insider view into the early days at Atari, you need to check out his excellent candid documentary DVD Once Upon Atari.
Now, finally, here's the good part...
- Each clear cast acrylic cartridge will be hand made and serial numbered. Game cartridges will work with the Atari 2600 Video Computer Systems (PAL or NTSC). I can't provide Atari 2600 systems on Kickstarter but they are plentiful and affordable on eBay if you don't still have your childhood game or are too young to have had one.
- Harmony FLASH cartridges come preloaded with Star Castle but additional games can be loaded onto SD cards (not included) and launched from a menu on the 2600 connected to a TV the way they were intended to be played. One SD card can hold every Atari game ever made. These cartridges are black and do not contain flashing lights.
The Star Castle CD contains everything you need to play the game on your computer and much much more:
- Star Castle 2600 ROM files for emulator/conventional cartridges and custom cartridges with internal lights
- Star Castle 2600 manual (pdf)
- Stella Atari 2600 emulator versions for Windows, Mac, and Linux
- Star Castle 2600 source code
- Star Castle 2600 source artwork
- The story of the games history, my inspiration, and the making of the game.
- Pictures: The game at video game conventions, the making of the game, electronics, and cartridge casing.
- Video: exposition of the game, interviews, making of the cartridge.
- Links! I've gathered a ton of information that I want to share but I can't include everything on the CD so I'll do the next best thing and share all of my sources for information with links about the game, video game history of that era, 2600 programming reference, techniques, and free tools like compilers and debuggers. Plus links to other versions of Star Castle (some FREE), press and YouTube videos, photos and much much more.
