My PS2 (Fat version) is working fine (Messiah 2 chip i think):
1) : the cd trays ejects normally but when you load the tray using the eject button, the tray will move very slowly back to the unit. is this a mechanical problem or dust issue?

2) whats the latest and best mod chip in the market now? so far i have no issues playing games but when i swap games, sometimes i do need to reboot.
