Hi, I've tested the .d64 file on my C64 mini black edition and the game loaded and ran perfectly. Maybe try it on a different USB stick?

Hello. Are you using PAL or NTSC... I tried both and any of these worked. And I also tried on a second C64 mini and I got the same results... I will re-download the rom game and try with different USB sticks. I will explain here my experience. Thanks a lot for your fast and kind response on my problem.
