I used Swap Magic 3.3 CD, eject that to get REFRESH TOC screen, insert Swap Magic 3.3 DVD, then last but not least, use slide Card or Flip top Lid to swap for Backup of TS3,
now game takes a while to boot, makes lots of strange noises, then Boots up fiine!!!!!
I have a Ver.7 PS2 with Swap Magic Disc's 3.3 with Slide Card
