A History of Copy Protection

GamerGirll1138 writes to tell us Next-gen has an amusing walk down memory lane with their history of copy protection. There have been some crazy schemes over the years to ensure that you paid for your software, everything from super-secret decoder rings to ridiculous document checks. "With bandwidth expanding and more and more games publishers exploring digital distribution, there's little doubt that we're entering a new phase in the history of copy protection and those who would defeat it. What's more, the demand for games as a chosen form of entertainment has never been higher. All this considered, it's impossible to believe that the cat-and-mouse game of piracy and copy protection will not reach new levels of intensity, with new technologies deployed on each side, and that some of them will surely create new hurdles for even those who simply wish to purchase and play the newest games. Ah, for the heady days of the code wheel."

Article sucks, but I remember two ...

[Richard W.M. Jones]

An extremely useless article even by slashdot standards, but I remember two copy protection schemes that sucked even more:

Lenslock - used by a few 80s home computer games. I'm fairly certain it might have been a UK-only thing. It was horrible. You had to fold this crappy bit of plastic a certain way and hold it over a part of the screen. If you were lucky, and your TV wasn't too large or too small, you might be able to make out the decoded letters which you had to type in.

And then one we used at work: Parallel port dongles. I used to work in electronic CAD and all the software used this, the result being you needed 5 or more dongles all plugged in at the same time to do any useful work. In the end we got someone in the workshop build a kind of "dongle motherboard" where you could plug in multiple dongles more conveniently than having them hang out the back of the machine, and more importantly pull them out to swap between machines.

Happy days ... No, actually sucky days. I'm glad I use almost completely free software now.

Rich.

We Copied That Floppy

[Doc Ruby]

I remember in the 1980s when game vendors started burning bad sectors into Atari 400/800 floppies on which they distributed their products. Their game's loader SW would try to read those sectors and abort if they weren't unreadable, thinking that pirates couldn't replicate them with just diskdup SW.

The Atari 810 floppy drive (the highest density storage available, like a 1TB HD is now, and the only game in town other than ridiculous tape drives, except for the extremely rare and stratospherically expensive 5MB Corvus HD) had a little potentiometer in its circuitboard controlling timing of the eletromagnetic signal waveform sent to the write head, that could be turned out of calibration to deliberately write a bad sector. So pirates would map the original's bad sector list, then copy the good sectors, then detune the pot, then write to the list of bad sectors - ruining them, then retune the pot and boot the copy.

Sure, that's pretty complex, voids the floppy warranty, and intimidates a lot of potential pirates. So instead, some people just stuck a disklabel to the edge of the target floppy, left the label sticking out of the drive, and grabbed that tab to jiggle the floppy while writing to each of the bad sectors - ruining them. Presto!

Besides, the pro pirates had the same mass floppy duplicators with the same programmable "write bad sector" circuitry that the original game vendors had, so the large, commercial pirates weren't fazed (pun intended ;) one bit (gotcha again >:P), but lots of honest people couldn't back up their games (which were sensitive to all kinds of transient EM, like paperclip collector magnets on desktops), and the vendors spent valuable time and money on worthless copy protection.

In fact, beating the copy protection was often more fun than the game. So around the world people were working to beat it, even if they never played the game again, but gave copies to friends just to show how ubergeek they were.

This cat & mouse game is in fact the exact model for all SW copy protection. It's become only a worse value waste for the SW producers, especially in content. They should use their only advantage, their earlier possession of the SW/content, to make big bucks at the first release, just like Hollywood does for movie premiere big weekends. Then let the pirates do their distribution work for free, and charge for support, customization, and subscriptions to upgrades. And build brands to sell their future releases.

Because "Don't Copy That Floppy" has been a losing battle, long before people would say "what's a floppy?"
