When I was a kid back in the 80's all the games I had for my Atari 8-bit were pirated, simply because there was no alternative under communist regime and no copyright laws whatsoever. You'd buy cassettes full of pirated stuff at all kinds of places and exchange gatherings and you could even get sort-of-manuals, which instead of being a copy a the legit manual was a bunch of general info and tips about the game written by some rando (the 80's equivalent of gamefaqs, basically ;D) on a typewriter and then copied on a garbage, 80's communism-grade photocopier - half the time you couldn't even read this crap, especially if whoever was printing those decided to slap on some graphics/logos. Fun times.

This honestly hasn't changed. When debugging modern games you still sometimes need to change how the game branches on the fly, and knowing op code for NOP saves you a lot of trouble. Though, many instructions on modern X64 are multi-byte, so sometimes you have to insert several NOPs. Fortunately, you can just check disassembly to see that the rest of the instructions have not changed, just like MVG does here.

The first game I remember using one of these wheels was Rocket Ranger on the C64 - which was completely unplayable without the wheel, even if it was 'cracked'. To get from one place in the game to another you had to enter how much fuel to use, info you got that from the wheel. I never thought about it as copy protection as a kid, it was just part of the game.

Like "what is the cost of using fireball?" or "what is the attack power of a diakatana?". It's manual was quite big too and indeed had charts for most of the games weapons, armor, etc.

That took a while, but a learned to type faster through that experience! Actually buying and owning original games back in the day was such a special experience that the younger generation will never know about! Great video.

As 40 yo man, that one brought great memories, we used to borrow games from one another and disassemble the wheels and copy them with pen and paper sometimes it took hours but it was fun to do with friends instead of homwwork

The first game I owned that had a code wheel was Legacy of the Ancients for the Apple II from 1987. This discussion reminds me, anyone remember the variety of hint books for the old Sierra adventure games? The earlier ones were printed in invisible ink and you had a marker that would reveal the answers (so you could only get the hints you need without spoiling everything). Later hint books had a red film "adventure window" to reveal the clues which were obscured with red ink.

Today on MVG: "Now let's fire up an emulator and reverse-engineer the copy protection." Tomorrow on MVG: "This week, we're doing cracktros."

since it was just a bend of compare, several steps still are open: a) check if some more compares are used. b) go some routines up to set the jump to starting point (the jump after the compare)and not to jump in the function. that would skip the check and askings completely and make the modify more clean. c) modify the executable, to match up changes in memory d) make some nice intro for the demo scene. i've seen assembler code last time a long long time in past ... thanks for the reminiscence

Some time in the '90s my brother got Hillsfar, War of the Lance, and Pool of Radiance from a thrift store. And Pool of Radiance did not include the code wheel so for awhile we just figured we had a game we couldn't play. Then one day my brother's friend told us to just use one of the other code wheels. And sure enough, it worked.

This really brings me back to my university days, where one of my assignments was to change the timer in Chase the Chuckwagon on the Atari 2600. Well done video!

I don't know anything about coding, and I know absolutely nothing about software development. I still find these videos sooo interesting. Thanks MVG!

Love that you showed the disassembly steps

I remember the original Worms on Amiga 500, it came with lots of black plastic sheets which were split up into rows and columns full of numbers that were also printed in black so you couldn't just make a photocopy of them in a shop. I borrowed it from a friend and typed down one whole sheet and when i wanted to play i just put in a wrong value until it asked for the one sheet which i had made myself a copy of.

Indiana Jones and the Last Crusade had a unique form. It had blue text with red static printed over it so you couldn't read it without a bit of red film. I think we were able to play with the contrast settings on the library's copier and got something usable out of it. What really sucked about copying these copy protection manuals was that you had to spend the money on copies just to try out the game. Since computers were so slow back then, it took quite a while to really get into a game and see what it was like. If you borrowed a game overnight from someone at school, you didn't have the luxury of playing very long. Especially when it took a good part of the evening to just copy the floppies!

Super interesting, as always. Especially the "live" cracking session :)

Thank you for taking me through the debug and crack process. As a child in the 80's; i had tried it out of desperation but didn't have enough knowledge or documentation even in late high school to be successful. I had enough knowledge to see the path to the goal; but not the skills to make it there myself. VERY interesting for a nerd like me.

Loved the live cracking. Thanks MVG

Very glad to hear the older theme intro/outro themes!

I enjoyed the live cracking part, I hope you'll do that again!

You said it in the summary, it was nice to get the box, code wheel, manual and such with the legitimate copy.

Good stuff as always. I can't remember if any of the games I played as a kid had code wheels, but I definitely remember the manual "Manual" protection.

tbh i did understand nothing of the cracking part, but was amusing to see lmao, great video as always, MVG!

Loved the code wheel for Starflight. The in game police would ask you for a code from the code wheel every time you left the spaceport. Even if you gave the wrong answer you'd be allowed to leave. But the cops would follow you. They would eventually catch you and ask for another code. I can't remember if it was after the second bad code or a third try but if you didn't give the correct response they would engage you in battle and basically curb stomp you. I always thought that was cool as hell.

Great video mate, that X Copy screen is too nostalgic!

The old Infocom text adventures sometimes had such a volume of collateral in the box that was vital to the actual gameplay, it was effectively copy protection but also part of the fun. And the Carmen Sandiego series which came with atlases and CIA world factbooks etc. -- it was so much a part of the game you never realized it was a huge pulp-based dongle.

I love seeing people play around with memory and commands and hacking programs. It shows you just how broad hacking is. You have to know low level code, high level code, binary, hex, common coding practices, a basic knowledge of the program you’re hacking, etc. there’s just sooo much to it. A good hacker has experience with all that and so much more and can apply that knowledge in many different strategies to accomplish some goal of bypassing security measure or changing data

I remembered I had the entire Gunship 2000 manual photocopied, and although the actual codes were only present on a few pages the manual had so much interesting stuff in it that it really needs to be included.

Very nice work 👍 Always love to watch cracking and reverse engineering stuff!

Nothing makes me click faster than a video on copy-protection and, hopefully, how it's been defeated. As far as that goes, yours are always top knotch. The little assembly tutorial was especially welcome, since I'm just getting into machine code level rom hacking

When I was a kid, there was a terrible bit of copy protection on an old SSI game called Gemstone Warrior - whenever you put the disc in and ran the game there was a 50/50 chance it would just go "Nope, this is copied" and not let you play (in fact there was a long scroll of text that lectured you for pirating the game.) The first game I ever had with a code wheel was Bard's Tale 2, and I had all the Gold Box games with their wheels too, but I had no idea so many other games used it.

Pirated copies usually came with txt file with few page numbers and corresponding codewords. If you get one you didnt have, you simply restarted the game until you did. Didnt even needed cracking, unless there was another level of protection. But it was trivial to overcome, most of times. That was true even for wheel codes, you just needed to know one right answer, then roll the dice.

It's always a good day when MVG releases a new video :)

I did that with Monkey Island 2's code wheel! It's clearly the best way, because it doesn't matter how impossible to photocopy the wheel is, and you don't even have to take it apart.

Here in the UK, around this time I remember the photocopier in the library was 5p per copy, a lot of money at the time when you add up all the pages. That was why I manually copied all the info I needed from Zaks's Programming The Z80 into a notebook rather than photocopy it (it was in the reference section too which meant it couldn't be borrowed out. That was a lot of sessions after school/on Saturday to get it all done).

I love watching this stuff while drinking my morning coffee 👍

This might be the best MVG video to date.

That was fascinating. A method even from many years ago, still useful.

I recall cracking Pools Of Radiance back in the day on the C64 but instead of finding the code that does the comparison, I searched the floppy disk to locate the list of correct words and changed them all to the same word. This was much easier to do than to disassemble the actual code and find the compare test.

This is the kind of tutorial. I will never, ever need but dam right I will sit through and learn.

Excellent video, as usual. Another game that had a fun method of copy protection was Rocket Ranger. It was clever as it was integrated in the design of the game. In the game you had to fly from a place to another, and to do it you had to choose the destination. But to select the destination you had to provide the exact amount of fuel (Lunarium) necessary to go from your current location to your destination, which of course should be read on a hard-to-photocopy table that came in the box. If you put a random number you would land at a random place at best, or more likely you would fatally crash on the ground. If you hadn't seen the original copy of the game, that would be very confusing as you had no idea why you kept dying :)

Nice to know about this topic by a programmer/Dev perspective while showing code.

... I needed this video 30 years ago when I was playing Pool of Radiance all the time

Loved the video. I cracked my first and only game by doing just that. I wold love to see more videos on the subject
