Huh, neat. Ive never seen that disc before. FWIW, i had 3 different 360s, but I dont remember which ones i would have used Og xbox games on. Likely my first one- it was the original larger style that was prone to RROD, but was purchased a few years after the 360 had been released. My other two were the later slim version. I dont have specific model numbers…the only 360 i still have has been in storage for a few years now in a different country, so i couldnt even go mess with right now if i wanted to 😅
