Hi, I didn't find a solution so I decided to post it. I already had 3 classic xbox games and they all worked perfectly, I added 2 more and now every time I start any one, the classic xbox logo appears but soon after, the console restarts before starting the game. I already have the compatibility file and even reinstalled it but still the same.
Do you have plugins active with Dash Launch? if so these can affect the emulator from working correctly in my experience. Are the games you are trying to play now even backwards compatible?
