Look man I had a dreamcast it broke down. And I do use nullDC for powerstone. I only used DEmul for powerstone because i wanted to check if it had the same problem with tomb raider, it did. Which means either two things DEmul overheats my pc which im likely to beleive because my pc shut down while using DEmul. Or there's a fixable problem with DEmul if two games have the same problem the problem is not with the games especially since powerstone works perfectly fine on NulDC. By the way the plugins dlegacy dv3 whatever they were called did not help infact the created a new problem so I changed the video plugin back to its original setup.
