Oh my god, y really wanted that was the disc, i has a disc of xenosaga a bit mistreated, and i buy a new one and have the same glith, oh, almighty sony please show us some mercy and let us play one of your greatest hits of ever, i mean xenosaga, that is almost for me my favorite, i'll wait for your mercy sony, and for play xenosaga, ty.
yep, i just got to this spot and sure enough, it did it to me too. 12 hours in and it looks like im gonna have to start over on a ps2. (long sigh) that is extremely frustrating. it says its sunny outside, but i swear, inside its raining.
I belive you are thinking about Xenogears (PSone). This is about Xenogears I, a PS2 game that isn't available to download from PSN. This games should play fine on a 60GB PS3, however it won't play past a certain point on the 80GB PS3.
This is what Sony's backwards compatiblity database states:
Xenosaga: Episode I - Der Wille zur Macht
Publisher: Namco Product No: SLUS-20469
