It took 3 minutes and 26 seconds to write the image file to disc. In ImgBurn I set the write speed to 4x as instructed in the tutorial and although the drive doesn't support that speed and instead used 8x it still burned the disc correctly. I have had success using Tesco 700MB CD-R discs using an external optical drive, an Optiarc BD-5740L. The software we will be creating ourselves will be in CDI format so we will have no problem burning to disc. The CDI format, however, is appropriate for burning to CD-R and may have had the game altered slightly (such as to force VGA mode) and likely the individually files will be accessible unlike on a GD-ROM disc.īecause ImgBurn supports writing Dreamcast discs from a CDI file you will need to obtain the CDI disc images only if you wish to burn to disc. You can follow a tutorial at:Īnnoyingly the link for the Dreamcast driver for ImgBurn is dead, however, I was able to find a different site hosting the files:ĭreamcast disc images can be in either CDI or GDI format with GDI more closely resembles an original Dreamcast GD-ROM disc.

You can burn your own discs (of games you already own) and test on your Dreamcast. As I already had a couple of burned games I tried them first and confirmed that they would run. Unfortunately not all Dreamcast consoles will be able to play CD-R discs so if you do plan to burn your software to disc then you need to check whether your Dreamcast can run CD-R's.
