Tales of Destiny 2 and Harvest Moon backup help please!

[rafe]

hi,
My PS2 is modded with a chip (not sure which) and despite having success with many games (see list below) I have not been able to play backups of Tales of Destiny 2 or Harvest Moon! Both of the game backups play fine through an emulator. I have tried using Alcohol 120 and CloneCD already. These programs have worked fine with my other backups. I have used the same media for all the games that have copied with success so I don't think it's cheap media or my laser (correct me if I could be wrong). Has anyone been able to play a working backup of these games on their PS2, if so, please let me know what you did to make the disc.

My working PS1 backups on PS2:
Suikoden 1 and 2
Star Ocean 2
Dragon Warrior 7
Final Fantasy Origins
Breath of Fire 3
Torneko: The Last Hope
Tales of Destiny 1 (not 2)
MegaMan 8
Chrono Trigger
Final Fantasy 5
Tactics Ogre

Thank you.
