first off i have magic 3.1 version 7 ps2 with fliptop/ swap magic cd 2.0 and 3.0 dvd 2.0 disc for double disc check games. i installed my chip (used) awhile ago (few weeks ago) the problems im having is with ps1 games and dvd rips. dvd rips: most of them dont load (t3, underworld, some more) t3 works when i boot it up with my old swap magic 3 so it's not a bad burn. ps1 games: i have backed up many ps1 games but some of them don't work it goes to the black screen at first but then it goes to the browser screen with a disc read error or it shows a pic of a black disc. the ps1 games that don't work are: bomberman world, thrill kill, nightmare creatures 2, pacman world, resident evil directors cut, and tetris plus. i have many other backups of ps1 and ps2 that work fine.
