How the Sega Dreamcast Copy Protection Worked - And how it Failed | MVG

Did you know that the Sega Dreamcast had very sophisticated copy protection? I didn't either. But its true. The Dreamcast had excellent security measures in place. With the custom GD-ROM format that was not readable by any consumer PC CD and DVD drives at the time it seemed that the Dreamcast would be safe from haackers. That is until one fatal mistake caused the complete breakdown of the security measures.
And ultimately some say was part of the cause for the demise of the Sega Dreamcast.

[@emmettturner9452]

Utopia supposedly reverse-engineered Datel’s Action Replay CDX demo disc from DC-UK Magazine to figure out how Datel was able to boot their CD-based cheat disc. Datel had more R&D and could actually pay professionals to break protections. Heck, they owned their own media pressing plant too (Thin Ice Media), which is how they got around protection for the PSX. They went around Nintendo and paid Panasonic/Matsushita for the tech they needed to make bootable GameCube discs too. That said, I suspect that the Utopia members responsible for the DC boot disc were probably Datel employees/contractors. ;)

[@Letstalkretro]

Some good points here.

[@emmettturner9452]

AfterBurnerTeirusu One would expect them to have access to the dev kit, or at least the software tools, since they had to do more coding. That was the easy part. There’s also a video from the about the hack resulting from a reverse engineered Action Replay CDX demo disc from one of Datel’s former partners (Larry Bundy Jr; 5 Hilariously Idiotic Gaming Screw Ups). Still, I’m interested in this other article. The N64 devkit software was so prevalent at the time that they had to explicitly ban it from coding competitions like POM’99. The DC scene wasn‘t so different.

[@emmettturner9452]

AfterBurnerTeirusu Yeah, it’s very possible that Datel paid a German group for an exploit they developed entirely on their own, but the AR CDX did predate Utopia Boot Disc. I recall a Datel rep on some of the scene’s IRC channels soliciting Game Boy coders for one of their projects (a programmable multicart that needed some legit content to justify its existence). They’ve definitely been known to reach out. ;)

What ever happened to the people that made the Playstation emulater called Bleem. Those guys reverse engineered the PlayStation so they could get their emulator running without breaking any copyright laws. Sony tried to sue the guys at Bleem but lost. Sony even went as far as to get someone to break into the Bleem office and try to recover sales figures on the emulator. Then came the Bleemcast to stick it to Sony. I wonder how it felt for Sony at the time, watching their games running and looking nicer on the competitions hardware.

[@emmettturner9452]

​@@BoomBox02 You might be mixing some of that up with Sony v. Connectix (Virtual Game Station) but, yeah, Sony sued both. Connectix demonstrated VGS to Sony in an attempt to get them on-board but Sony didn't want any part of it. At that point they were using Sony's BIOS. Sony's refusal sent them back into development to make a functional BIOS substitute that didn't break any copyright laws. Of course, Sony still sued in an attempt to set a precedent and make all similar emulation illegal on the basis that it infringes on IP related to the rest of the platform's technical specifics. Luckily, Connectix wasn't such a small company (makers of VMWare) so they were able to defend themselves. When Sony sued Bleem! it was for "Unfair competition" and the use of screenshots to market it (deemed "Fair Use" by the courts). Imagine if Sony had partnered with Connectix instead and attacked the makers of Bleem! with that earlier lawsuit instead, which would have set a bad precedent for all of emulation. D:

[@GeoNeilUK]

I'd like to know about this, especially considering emulation of disc based systems. You see, I'd just assume that the emulator of a disc based console would be able to read discs intended for the console it's emulating, but I do know that Dolphin (Gamecube and Wii) only works with ISOs and I'm not sure about other emnulators eg RPCS3 (PS3) So I'm guessing that copy protection is something emulator authors have to get past not only on ISOs but also on the discs themselves.

You can actually read the "High Density" part of the GD disks in certain standard PC CD drives. It involves burning a CD-R first, which contains the same type of TOC info that is typical for a Dreamcast disk. You then load the CD-R, let the drive read the TOC, then do a disk swap. Some CD-ROM drives have a wide enough tolerance for the spindle motor speed to allow the disk to spin slow enough, and the "HD" track to be dumped. The trick sometimes involved setting the laser sled switch after the disk swap so that the laser will start reading the HD track first. This can definitely be done, as I did it myself many years ago. The HD track really is just a standard ISO9660 track, just burned at a faster rate. (and the GD drives have custom firmware to read the second TOC, and access the HD track.) ;)

[@electronash]

Do you have the other SDK docs, with the "Sega Packet Interface" PDF? There's also the System Architecture PDF, which I refer to as the "Dreamcast Programming Bible". Not that I'm very good at that side of it. lol The closest I got to coding anything for the Dreamcast is when I did the first ever tests of an IDE HDD as a Slave device on the G1 bus (alongside the GD drive). I modified the KOS examples to access the data on the HDD (or CF card), and print the sectors as hex. I then designed a simple passive adapter, sent a few to Mr SWAT, who then added support for IDE devices in Dreamshell. And so, the G1-ATA and IDE mods were born. ;)

You could disc swap to rip Xbox 360 games in img burn too. Or you needed a kreon drive

[@MrRobarino]

Did you even finish watching the video? He clearly stated in the video that you can read GD-ROM disc with certain model PC CD-ROM drives. You aren't sharing any new information here.

[@electronash]

@@MrRobarino That was using specific firmware which can allow specific drives to read the HD track without further modification. The method I'm talking about is forcing a generic CD drive to read the track, by moving the laser sled zero-offset switch. Two completely different methods, as the second way involves physically modifying the drive, and can work on many models, not just the ones stated in the vid.

[@electronash]

(the wiki article shown in the vid may have contained more info on that method, but the link wasn't included in the vid description at the time of posting, so I couldn't easily check it.)

[@neocraven]

Something you didn't mention - when I first bought my Dreamcast, I was told of the battery removal trick. If you remove the internal battery for the Dreamcast, as well as tie back the clip that detected the GD-Drive door opening, it allowed you to play multi-region or backup games. You would insert a legitimate disk, and the Dreamcast would read the files it needed to boot whilst at the same time asking for the current date/time. You then wait about 2 minutes for the disk drive to timeout and stop spinning the disk. Then you could open the drive door, change the disk to a different one, and then select continue on the data/time menu. Worked really well but I remember you needed to boot different original games depending on the backup you wanted to boot...which makes sense now that you've explained the ip.bin file containing data for the game :)

Funny that burned GD-ROM discs still can't be self booted. Of course finding blank GD-ROM discs and setting up a burner really isn't worth the time, but even now if you ever get a hold of a burned GD-ROM the only way to boot it up is using the System Disc 2. The System Disc 2 wasn't reversed either, so you have to track down a legitimate copy of that as well!

@@BADSeCt0R2XP Sega bungled up with the Genesis addons and the Saturn. The 32X was kind of pointless as most of its games were merely slight facelifts of existing titles even though the hardware does have potential. The Saturn had a lot of flaws both on part of the hardware and how it was marketed. It was infamously rushed to counter the PS1 in the States, and its hardware was and still is a *nightmare* to develop for. That certainly accounted for why they were in dire straits at the time.

ARS DC was so far ahead of its time, especially in Japan where the mouse, broadband adapter, I believe a camera, and (if it was made, a vmu MP3 player. So D.C. Had nearly all widely used PC components (except internal storage). Keyboard, mouse, live audio chat, modem/broadband, web browser and (I've heard rumor of a basic but very functional "Office-type" word processor & spreadsheets), live video chat, web camera. I'm betting some found ways to use the expansion ports on the back to connect printers, and the ILLUSTRIOUS VGA box/cable to play 480p so sharp on a pic monitor. Dreamcast, aside from storage limits had most bells and whistles of a $3,500 pc at the time for $200. Buying all the options adds up some, but not late 90's/early 2k's absurd prices. also had online multi-player. And my favorite: lots of killer games and arcade ports you could play by just pressing "power"- no crazy conflicts and patches and incompatibility that was so sloppy on pc- like physical jumpers, that made me spend days trying to get one crappy pc RPG to work with hours of tech support.

We came to the conclusion that the only way to keep the game from getting ripped 0-day was to interleave the game data on the disc with junk data and artificially inflate its size to the max capacity of the GD-ROM, and the lead coder said he'd try it. I THINK this worked, because the main DC warez group had "refused" to release it on day one, saying "You guys don't deserve it because you take us for granted" or something along those lines. (Of course, they wound up getting around it a week or two later, as expected.)

@@yoshi314 he did it on the original PlayStation, not PS2 which is way more secure.. and yet not because of external media booting. But hey you cant play burned games by just burning a certain image from stock so they did one up on sega

Nice vid! ps: there's no one better than you mr. MVG to bring us a series of "games locked on a single platform" and how to play 'em in 2019. CXBX emulation, x360, ps3 and wiiu are getting better and better. Would be kickass to see how these perform (properly played, controllers and all) versus original hardware. You're the man up to this task, mvg!

[@nimrodlevy]

I love this kind of videos!! I wish more could explain like you have, for example what dr. Abrasive did to unlock the saturn i didnt understand any of what he said. Billions of thanks, intresting and enriching! Although im not very good with english, i greatly like your educational videos! Thanks mr.

[@JimLeonard]

Excellent coverage. One thing I'd like to add is that some games had more than 700MB of data on the GDROM (video files mostly) and those couldn't be copied over straight; we had to RE the video format and come up with tools that could transcode the movie and audio files into smaller sizes. In extreme cases, 22KHz ADPCM stereo audio would be turned into mono. The quality suffered, but it worked. The only two games that were too big *and* had no movies/audio to transcode were D-2 and Skies of Arcadia (all cinematics were in-game, and the audio was mostly speech which was already 11KHz mono IIRC). In both cases, the data had to be split onto two CDROMs and instructions were given on when/where to swap discs. Kudos to the developers of those games!

[@ComradeJared]

I used to rip games for ReviveDC. D2 is a very curious one that we looked at a lot. The ADX decoder in that game is actually tied to the sample rate of the audio files in the game. Trying to reduce the size of the audio files results in scrambled audio. It's very bizarre and it's the only game (to my knowledge) that had a decoder that was hardcoded to the sample rate.

[@JimLeonard]

@@ComradeJared Nice, what was your handle back then?

This is because Echelons method of booting was released and most DC game downloads today used a prepared ISO with the exploit already in place.

It's funny because one of the main cause of Dreamcast's copy protection breach was because some Action Replay demo disc

Great video, i would love to see more about the Dreamcast and other copy protections. Love that stuff.

[@james_nolan]

Always enjoy your videos! Very informative as always. I've considered buying a Dreamcast just to rip the games to use with emulators, but does that SD Card method work for dumping the BIOS as well?

[@jonj736]

1:28 If you really know your SEGA consoles you'll know the Dreamcast was actually the 3rd SEGA console to use an optical drive...

[@swfreeD]

technically the 4rth if you count the portable sega cdx

[@NickBailuc]

@@swfreeD why would cdx and sega cd be counted as 2 distinct consoles?

Very interesting. I look forward to future videos covering this topic.

[@Windsorsillest]

I just want to say thank you. I really enjoy your videos and learning about emulation etc.

[@AWalYT]

If a dev kit has a memory viewer, deciphering a scrambler is only a few RAM dumps away. To be fair, it was much more sophisticated than the BCA of the Saturn discs...

[@NaokisRC]

But took a lot longer to get a mod that worked around the "fortress" of a cd drive controller. My favourite is the mega cd which has no copy protection at all.

[@segaunited3855]

Saturn was better. Sophia ran Checksums and Lockjacking. Dreamcast used GD-ROM. GD ROM is basically HC CD ROM with all TOC packed on one layer. Dreamcast Copy Protection was all Software in the Whitebook of GDROM itself.

[@bhirawamaylana466]

BTW about Dreamcast anyone know where I can find Dreamcast Homebrew community ? There many result in Google but I don't know which one still active.

I love your videos about copy protection! One thing that I’d like to suggest is that you make a video ranking in your opinion what are the 10 hardest to defeat console copy protection schemes.

My understanding was the key to this process being discovered when Gameshark(or other similar software) sent out a demo disk in a magazine. It allowed you to boot and play burn disks. This was the first crack in the armor.

[@datriaxsondor590]

9:19 Not necessarily 100%, as I have a revision 2, which boots backups. Ironically, I have a rev 0, and a rev 2 Dreamcast, and not a rev 1, meaning I can't use gdrom emulators atm, unfortunately. Nice vid as usual though. Was a nice watch.

[@sabata414]

How do you tell the revision of DC?

[@TrimeshSZ]

@@sabata414 If you have a NTSC:U/C or PAL console, then look for a number in a circle on the label - that's the revision. If you have a NTSC:J console, you have to take it apart.

@@TrimeshSZ thanks

[@Deltarii]

So basically these where the original r4 cards?

[@HarrisonMartinson]

7:09 From what I gather, there was no unscrambler. I think the hackers just scrambled it in such a way that the scrambler would actually fix it. To make this concept easier to understand, let's use the Caesar cipher for comparison with a key of 1. A becomes B, B becomes C, and so on. Let's say the word needed is "HI". That would become "IJ" and therefore invalid. Instead, you could input "GH" which becomes "HI", which _is_ valid.

[@FreeJulianAssangeNow]

Extremely pleased that you’re covering copy protection! - I really can’t wait for the next episode! - However, this new series might be a double edged sword. I bet tons of big name hardware developers watch your content like a hawk and will be creating notes to avoid mistakes they’ve made in the past.

[@StriderVM]

They do not need KZbin channels like this to monitor security. They will be on hacking groups and release groups forums instead.

Fantastic video MVG! I just recently got a Dreamcast for Christmas and I’ve been playing it more then my current gen consoles. The library is just that clean! Question for you though: I noticed you mentioned the SD reader on Dreamcast and as someone new to the whole Dreamcast scene, it’s the first time I’ve heard of it. Where did you get yours and/or are there any plans to cover it in a upcoming video? Love the channel and keep up the good work!

Utopia was sent a dev kit by accident and it had a bootcd that allowed dev's to boot any code with any dreamcast,Utopia just added the raindear like most crack intro's

[@darcagn]

the disc you're referring to that came with devkits is a SYSTEM DISC 2, but that is not at all like the utopia boot disc and is not how the utopia disc was made. You can see that the Utopia disc uses the exact same little endian/big endian binary obfuscation trick on the disc that the GameShark/Action Replay discs used, because they jacked code from that.
