There are two versions of Utopia still in circulation - use both as they have different compatibility (from my experience). When in doubt, use a Utopia Boot CD to launch games that seem unlaunchable (Region issues) or an Action Replay CDX (Not recommended). ALWAYS aim for CDI images rather than ISO or BIN/CUE - the latter have issues when it comes to multi-ToC discs. NEVER convert Dreamcast images unless you know what you're doing - you may damage the image by messing up the ToC's. There is also a chance that your Dreamcast laser is dirty or requires calibrating if the unit was neglected for a long time or, the other way around, if it was grinded. The disc is badly burned, it's low quality or the image is damaged. Your Dreamcast does not detect the second ToC and thinks that you placed a single-ToC CD-ROM into the drive. Unlike a CD, they have two Tables of Contents - one with Audio/Data (standard Audio and, for example PC wallpapers like in the case of Sonic Adventure) and one with the game itself.

If you have a BIN/CUE file, select the CUE file. Find your file by clicking the ‘Browse’ button in the ‘Source’ section.

Or you can also right click on your file and select ‘open with ImgBurn’.
