Dreamcast CDI Burner version 1.04 by Alex Free. Released July 5th 2020.

CDI is the proprietary format of the Windows only software DiscJuggler. It is a very popular format for Sega Dreamcast software.

This app can burn a Dreamcast CDI file to a blank CD-ROM using your Mac's internal burner. The resulting CD-ROM is bootable on a Sega Dreamcast console, making use of the MIL-CD exploit. This exploit does not require any console modifications.

Revision 0 and 1 consoles can all be exploited. If you have a revision 2 console it may not be able to use the MIL-CD exploit to boot burned CD-ROMs. To find out the revision of a console, flip it upside down and look for the number 0, 1, or 2 circled on the bottom label.

This software supports all 4 Sega Dreamcast CDI File format types, listed below.
Data ISO+data ISO.
Multi CDDA WAVs+data ISO.
Multi CDDA WAVs in an ISO+data ISO.

Compatibility - Mac OS X 10.3.9 and above, PowerPC G3/G4/G5.

Copy '' to '/Applications/'. If is ran anywhere else or named differently you will be prompted to copy it to '/Applications/'.

Insert a blank CD-ROM into the internal burner of your Mac. When Finder asks what to do with this disc, click 'ignore'.

Double click '/Applications/'. A window will open allowing you to select a CDI file. After selecting a file you may be prompted for your account password. This is required to give cdrecord the privileges required for successful burning. After entering your password if prompted, simply wait for the burn to complete, you may monitor the progress made in the Terminal window.

Source Code Installation

Tested with Xcode 1.5 on Mac OS X 10.3.9. Install Xcode. Next, open '/Applications/Utilities/', 'cd' into the extracted source directory, and execute 'sudo ./build'.

Licensing And Credit itself is released into the Public Domain.

CDIrip version 0.6.2 has no license, and was released as 'source available' in 2002. CDIrip version 0.6.3 was later released in 2004 under the GNU GPL v2, however Big-Endian PowerPC support was stripped. For this reason 0.6.2 is used instead of 0.6.3.

Cdrtools version 3.02a09 is released under the LGPL v2.1.

For more information, see the 'licenses' directory in each release.

#3 contains some extra Dreamcast goodies and software.

Architecture: PPC

Mac OS X 10.3.9 and above, PowerPC G3/G4/G5.

I bought Soul Reaver for the Dreamcast when I was 10 years old, a very endearing game indeed

Great to hear, if you have not played it already I highly recommend soul reaver. If you know of Classic Game Room on YouTube, I’d take a look at season 1 or any of the other Dreamcast reviews as well.

Thanks for all the testing. As always let me know how it goes.

Really looking forward to test your software out because for some reason my Wintel makes broken DC games (since I upgraded to 64bit Win7) and my Pioneer SuperDrive has been working flawlessly ever since I cleaned it; just have to find the right idea as to what to burn?

Thanks for the updates and all your work. I'll have more time soon to start test burning some games. I have a whole bunch of images that a friend had to burn for me on a pc. Wouldn't mind seeing how they work with your program.

I finally came across this issue trying to burn Skies Of Arcadia CD 1, so I got to see what a CDI file that doesn’t work looks like. Basically it’s a 4th type of CDI file I didn’t know existed, DATA(CDDA In an ISO)+DATA(ISO). I’ve gotten support now working for this in version 1.0.2. Now all CDI files will work, those duds must of all been this type.

Thanks! It sounds like the duds are just bad files, can you try burning them in other software?

Cross Yu Suzuki off the dud list. Burned another image file and it completed/ plays successfully. Did have an issue with one Resident Evil disk. Disk 1 burned and played fine. Disk 2 finished successfully but when inserted seems to start and then kicks me back to the 'play' menu. And because it looked like it burned properly, stupid me closed the terminal window without saving. I'll track down a different image file for it and test again.

The best thing for me would be to simply copy the entire terminal window contents after a failed burn and put it in a comment here. You’ve been very helpful with testing this app and I’m very grateful for your testing.

I’m going to seek out that CDI and see what happens, I’ll get back to you ASAP!

Sure, I'll go back and retest said duds and try different images if I can find some. Yu Suzuki Game Works was one in particular that hasn't worked yet but I got a couple of different images from other sources to test. I'll also try to organize some screen shots of the terminal window I made that might help track the point of error if you tell me what to look for Smile. Unfortunately, there are lots of them and they're a mess on my desktop right now. Off the top of my head, most errors were before the burning process began, leaving me with 4 second audio disks. I'll check back in when I systematize things better. Cheers

Feedback is always appreciated! When you say a few duds, could you elaborate? Does the burning complete all the way, but the Dreamcast doesn’t boot them? Does the same CDI file create bootable CD-ROMs with DiscJuggler or IMGburn+DLLs? What revision Dreamcasts do you have?

Duds are concerning as this should just work with any valid CDI file. I have come across a CDI file that was just not bootable before, it was a home brew I guess not put together correctly.

Can you try different images for said dud game?

Please let me know if other burning software can burn a CDI file successfully that this one can not. Specifically if there is any way you can show me a dud file that would help. Thanks again.

It’s very important that the updated app is in /Applications when opened, but I’m sure your doing this.

If burning does not complete all the way, maybe it’s a massive file? I’ve been told Mac optical drives are not over burning friendly.

Holy crap, CDDA support is indeed functional. Had a few duds but most of disks I tried, burned properly. I will continue to test and give more feedback if needed. The Dreamcast is easily my favorite console (I have 2 so i can easily play vga and non vga discs. I have a pretty big library of (purchased) games already but it's so cool to be able to explore the Dreamcast's diverse library. Great work and thanks again, alexfree.

Have had "Disco" work a time or two, but your app really is just what we all needed. Thanks again.

Multi CDDA support is now in version 1.0.1! I am very happy you have found this useful. Liquid CD never worked for me, mid burn I would get a "drive unresponsive" message every time. I made this because nothing else worked, and now this supports all Dreamcast CDI file types. Let me know how it goes, thanks for the feedback. Never again will I need to borrow a Windows computer.

This is pretty great. My previous go-to burning app was liquid cd on a powerbook 1.5 ghz, which did really well with data/data games, not so well with audio/data files and simply would not burn readable disks from games with CDDA tracks (which read as single audio files). With this program, I was able to burn quite a few mixed audio data disks (cave story, Advanced Daisenryaku with english patch, gameboy rpg rom collection and a number of home-brews for example). Still no success with CDDA games but to hear you are planning to implement this feature is exciting. Thank you alexfree-great work!

Definitely happens with some images and CD-R sizes, I’m not sure how far a 90 minute CD-R could be over burned but I know something like Jet Set Radio at ~900MB will never make it on a 700MB CD-R. So far I’ve found this to be the exception and not the majority, and this will work just as well as DiscJugglar can once I add that multi CDDA support later today.

I think replacing the GD-ROM drive entirely is an amazing accomplishment within the Dreamcast community, but I’d always want at least one Dreamcast with a real optical drive.

The only issue is that often CDIs just need more space than can fit on even a 90-minute CD, if the person who made it didn't re-compress, or worse-yet delete items like movies. This is one place where emulation obviously rocks. Even just Disc-Emulation in a stock Dreamcast eliminates this issue completely - reading off an SD card.

I’ll tell you what, next version will work on Panther and above, G3/G4/G5. I also will be adding multi track CDDA support, I didn’t even know that was a thing until I tried burning HydroThunder earlier. After that is added, you’ll never need Windows for Dreamcast CDI’s.

Half life is excellent, I’m about half way through it. If you try the app let me know!

BTW Three Unreleased games VERY WORTH playing are Half-Life, Propeller Arena and Millenium Racer. All 3 are Final/R.C. and somehow didn't make it to store shelves. Images are really easy to find online. If this app doesn't work, then try this on Windows 10 worked on everything I tried.
