This disc tends to lock up in display weird video images on my screen. Dreamcast games are a little subjective. Not necessarily a fault of the disk. The laser in my system could be slightly out of alignment, However it does work with all of my other disks. When you are buying media specifically dreamcast games that are almost 25 years old They can be a little quirky from system to system.. I bought this more what year pampflet in case cover than anything else, So in that sense I am happy.
