Our Video Game Heritage Is Rotting Away
eldavojohn writes "There's been a movement to preserve virtual worlds but MIT's Tech Review paints a dire picture of our video game memories rotting away in the attic of history. From the article: 'Entire libraries face extinction the moment the last remaining working console of its kind — a Neo Geo, Atari 2600 or something more obscure, like the Fairchild Channel F — bites the dust.' Published in The International Journal of Digital Curation, a new paper highlights this problem and explains how emulators fall short to truly preserve our video game heritage. The paper also breaks down popular SNES emulators to illustrate the growing problem with emulators and their varying quality. Do you remember any video consoles like the Magnavox Odyssey that are forever lost to the ages?"
There's a very interesting project aimed at "decapping" chips from arcade motherboards. They burn the tops of the chips off with fuming nitric acid until the silicone is exposed, and the silicon is then put under a microscope, and the resulting image is then somehow processed to obtain the ROM's actual contents. I don't see why it couldn't be applied to consoles as well, if necessary. See http://guru.mameworld.info/decap/ for more details (and how you can help).
As to the article's position that emulation is not "good enough," well, perhaps not. Even assuming we have the exact decapped ROM contents, full documentation, and an absolutely perfectly coded emulator, we would still lack the original hardware - specifically the controllers and display. I used to play games on my Commodore with an old Atari 2600 joystick in a little 13-inch television. Its a tad different with my USB gamepad on my 22-inch widescreen LCD monitor, and there just isn't much for it.
Bigger problem with the Vectrex is that it used a vector (X/Y) display. Although you can now draw lines on a raster monitor that are very smooth, and you can do glow effects that look pretty nice, it's not the same as drawing a straight line from point A to point B. No pixels, just phosphors emitting light.
Anyone who's played Asteroids on the original coin-op hardware (or even just played around with a CRT-based oscilloscope!) knows that if you dump a CRT's electron beam onto a single point, you get a spot of brightness that's radically brighter than a single white pixel on either a CRT or an LCD monitor.
For emulation purposes, I could live with rasterization. Sometimes, preserving the original hardware's important. Fortunately, there are communities in both the coin-op (big convention two weeks ago in San Jose) and console (big convention this weekend in Vegas) communities dedicated to keeping the hardware alive long enough for the software to be preserved (and as much as possible, the hardware to be reverse-engineered for emulation purposes).
Behold, a CRT vector graphics implementation of Asteroids. The article (in German) describes the whole project. The logic hardware is recreated as an FPGA "program". An X-Y-capable oscilloscope can be used as the display.
