On Xenia Canary, the Xbox 360 version of Fifa 08 boots and is very playable.
There are some rendering issues here and there, like missing goal nets. Some stadiums on both Rpcs3 and Xenia have overbright exposure problem. This is not normal and most probably an emulation error. On those stadiums, you're better off playing with match time set to night.
Being that said, the Xbox 360 version of Fifa 08 seems to be the definitive version since 3d grass is rendered on this one, as well as the normal maps and bump maps are not inverted like Ps3 port.
Here's some footage of the X360 version running on Xenia Canary on my PC:
Game doesn't look dark like this on my pc. But for last 4 months, every video I upload ends up looking darker than the source video for some reason. So the game should look brighter than the video.
