Help with install messiah 2 ver 7 ps2

[rottenrod]

Tried my first mod on ps2. Wow. Had it apart and together 6 times now. I was able to boot up dvd, and originals but would not boot up backups. Took it apart and cleaned numerous solders, and put together. Now it boots up originals and their backups but not dvd player or backups of ps1. Any help would be appreciated. Thnx
