Alright, so I was playing Banjo Kazooie on the newest release of PJ-64 when I wanted to switch games and wondered if it had IGR. I hit L+R+white and nothing happened so I started trying other combos. When I pushed L+R+black+back my eject LED went red and some noise was made. Intrigued I did it again to the same results. The game kept playing so I decided to get up and restart it. I rebooted and got the original BIOS. Thinking something just got knocked loose or something I rebooted again, the original BIOS still coming up. Now, I'm not an Xbox pro but I don't consider myself a newbie, but I've never heard of a button combination to flash your Matrix when it's in Mode 3 (loading and ejecting will restore normal BIOS). So what have I done here? Thanks
