I've been using swap magic for a long time and I thought I was using bad media because everytime I booted a backup, there would be a red flash which I thought meant that the disc was bad. The game would eventually stop working after awhile. I thought the red flash meant everything, but I recently booted a BRAND NEW ORIGINAL game and there was a red flash! The game runs fine! I tried this on all my other newer original games and they all show a red flash. What is the use of this red flash?
