Hi guys, I'm brand new to the Dreamcast scene. I recently got the console about a week ago, along with a copy of Sonic Adventure. Most of the time the game runs fine, but now it's starting to only work about half the time. Sometimes when loading a new area, the screen will go completely black, yet the disc is spinning. When I go to reset the Dreamcast, the disc goes to the SEGA logo but then boots right back to the home screen, with no errors or anything. There aren't any huge scratches on it either, only a very small one. Strangely enough, if I unplug the power supply and hook it back up, everything works as usual again. Could this potentially be a power supply issue, or is it the disc drive? Thanks for your help!
