- Today, join me whilst I explore and try out three different types of 1980s anti-piracy copy protection methods (similar to DRM), including the infamous Lenslok. The games I will be looking at, are: Teenage Mutant Hero Turtles on the Amstrad CPC, and Jet Set Willy, plus TT Racer on the Sinclair ZX Spectrum.

Most memorable for me was The Secret of Monkey Island on the Amiga, a rotating code wheel from what I remember.
This channel confuses me so much. It feels like you came out of nowhere and suddenly there's this professional broadcast standard level of production quality with someone clearly used to presenting, as if she'd been doing this for years. Love the content, so not a complaint. 😉
Not copy protection but when I was 18 or 19 I found an old copy of Leisure Suit Larry, which is an 18+ rated game. It had a series of questions to prove you're an adult. Many of which were about "recent" history and politics. The thing is, since I was an adult in the 90s, not the 80s, I didn't know the answers. I had to look them up in the encyclopedia.
Did nobody from the team who invented the genius black-on-dark-red "copy protection" method think of someone just rewriting all the codes to a
After 30+ years of playing Sid Meyer’s Railroad tycoon, I’ve NEARLY memorised all of the train images you need to identify on copy protection! 😊
The thing they did not bargain on was just how much spare time and determination we had as kids
The most amazing thing that happened to me in the 80s was loading a game called Freddy Hardest from the wrong tape and needing a 4-digit code to get to the second part of the game. My friend hit some random keys and... they were the code. We were both in shock.
How is Kari remembering all this stuff from the 1980s, she was only born 15 years ago, is she supernatural?
All you would have needed to defeat the first copy protection was a pencil, some paper, and a lot of patience.
The coolest copy protection from the 80s that I remember used a laser to burn a hole through the disk at a certain track and sector. When the game started up, it tried to read that track and sector. If it succeeded, then it knew the disk was a copy, and the game didn't load. If it failed, then it knew it was the original disk, and the game loaded.
1980's coder here (Sinclair ZX81, ZX Speccy, Beeb Model B & Straddy CPC6128)... The cracking scene was also a pretty big deal at the time (Still is, to be fair!). Software houses thought they were safe because they'd sell their compiled games written in Assembly code, but there were plenty of disassemblers available for most platforms, which enabled people to reverse engineer game code and insert functions to override, circumvent or obliterate copy protection routines.
Just casually has a photocopier lying around for the first copy protection method. Love it 😂
I remember cracking the colour code sheet for Jet Set Willy on the Spectrum whilst in college long after the game was released. I was teaching myself Z80 assembler at the time.
Jet Set Willy! Yay! My favourite pre-2000 game. I have an unopened copy of it on ZX Spectrum which I'm very proud of. 🙂
That Lenslok is a bit like a CAPTCHA challenge where you have to figure out the characters 😬
I remember lenslock on the sinclair 48k. As a 7 year old I had hell getting those damn things to work.
I taught myself assembler in 1984 and I’ve tried many times (and succeeded quite a few times) to crack the copy protection. It was a matter of going through the code step by step until you found the subroutine that handled it, or you found some data block with a bunch of hardcoded codes. Very time consuming, but great fun.
The color grid is interesting. I don’t recall seeing that in the U.S.
I definitely recall having to look up things like "page 9, line 23, word 4" in the instruction manuals of old pc games. There were also some games that had a piece of transparent red film that you would have to hold up to a red garbled page in the manual so that you could see the codes. They got pretty creative back in ye olden days.
"Zak McKracken and the Alien Mindbenders" had a similar approach to the Turtles game (i.e. looking up a code on a sheet). The main difference is that you could start the game without a code, but you'd be prompted when you bought a plane ticket, i.e. you'd be stuck in one location without the code sheet.
