PS2 game Compatibility issue

[Prophet X]

Anyone else think that Rocky Legends runs like crap on ps3? The game is loaded with bugs and glitches. In Drago's training rounds, the screen flickers violently. Also, sometimes you can see "cracks" in the characters polygons, and various other graphical errors. I know that for the longest time, this game was on the unsupported PS2 title list, but subsequent updates have fixed most of the major problems(it's come quite a long way), only it seems that the progress of updating compatibility with this game has gone MIA in the long stream of recent updates. Honestly I could really could care less about the XMB. I know that Sony never promised that ps3 would ever have 100% compatibility with all ps1/ps2 titles, but it would still be nice.
