I just got a PS2 and put a DUO 2 SE modchip in it. Most of my backups work but two don't. "Def Jam Fight for NY" and "Fight Night 2004" These games load and start most of the time. But will always eventually freeze. If I press the eject button the DVD ejects and closes quickly. The game with run for a short time and then freeze again. I can continue to unfreeze it by ejecting and closing the DVD. Also when the games freeze there is a clicking sound.
