My tested games so far (All PAL)
Mario Kart - Game crashes after the 1st race in the GP. Also see above.
Super Smash Bro's Brawl (DVD9 full game) - Crashes/Hangs on the 1st loading screen after the save game screen (If no save is created).
Resident Evil Umbrella Chronicles - Other thn the movie stutter, and long loading the only problem with this game is data is streamed during gameplay for the next sequence. During this the you can move your crosshair around but the music will loop and will have to wait aroun 10-20secs till the game continues. Upside to this is having more time to grabbing items, ammo etc...
Battalion Wars 2 - Game plays fine although during campaign the FMV's are rather lengthly and stutter badly and cannot be skipped so prepare to wait a while.
Wario Land: The Shake Dimension - Again FMV's are really long and stutter badly. They cannot be skipped so alot of patience is needed. After this the game is only playable up until the end of the 1st level where the game hangs once its completed.
Mario Strikers Charged - Crashes frquently on various loading screens. Also has some strange polygonal glitches whilst on the start up screen and a few of the menu's. Game plays well if you get the chance
.
Metroid Prime 3: Corruption - Game plays fine, but like every1 else doors take forever to open if at all so breaks the game.
Mario Party 8 - Seems fine so far although i haven't had time to play a full game. Only problem i have come across is the tutorial video's for the mini-games stutter...
Hope these help people, will have a few more later.
