.I have an original Devil May Cry 3 demo CD disc. .I use slide card and swap magic CD version 3.0 . .I think I had a V4 or V5 Playstation 2 becuase it has an electical warning stamp at the bottom and 8 screws. .When I choose to press X (normal boot), my PS2 can read the intro movie, but after I select MISSION START, the screen went blank. .When I choose to press Square (special boot), my PS2 can't even read the disc at all. the sentence "please insert a Playstation or Playstation 2 format disc" appears .this game is NTSC/J . I tried both normal boot and special boot for all NTSC,NORMAL,PAL video mode but I still can't play the game. Please help me.
