Thanks to current WIP, the somewhat famous Gran Turismo 4 goes ingame! Expect plenty more to come

wow thats freat. i have gt4, i will try later

Ingame? I'd say its fully playable.
At least my NTSC version is

Most problem it has are caused by GSdx, so here's some tips:
Use version 0.1.7 of the plugin.
Set internal resolution to 1024*1024.
Configure the game to use progressive scan 480P
Set the brightness to 0.

I tried a few rounds, and got no hang or crash whatsoever

Also don't mind me not noticing this thread is from 2005, Gizmo_X didn't either

You both just failed miserably
