Yeah, but it actually brings up the menu and lets me select a character/fighter, starts the fight and in the middle of the fight will blank the screen for a couple seconds and then come back. I don't think that is the issue with the controller check during boot.
And if it was a power supply issue, or cap issue in the console, I would suspect to have the issue occur on all games, not just KI:Gold. As stated previously I played Zelda:OoT for 4 hours straight over the weekend without seeing this issue, and played a couple hours of StarFox 64, again, with no issue. But the moment I put in KI:Gold, about 30-45 seconds into it, the screen will blank for a few seconds and come back, and then repeat in another minute, and continue doing so until turning off the system and changing the game...
