I have this issue. The console freezes after 15 minutes running. Try returning it if you can as it seems to be a hardware problem. In my case I can't return because I already opened it and did a couple of soldering points. I thought I've burnt the board while doing the soldering points but it's possible to be a problem with some other component (NAND / RAM / processor).One issue I came across today was that in the middle of the robotnik battle in sonic 1 the game froze on me and i couldn't get out of the game is there anyone else experiencing this
