try Guide: Installing CFG Loader
force the videomode in the loader settings to your region's signal (PAL/NTSC whicever applies).
250rev20, 249rev17 should work.
already re-dumped the game to the harddrive? does it play the intro sound when you select the game?
good indicator that you "only" have to find the right setting. also altering the gamelanguage to load to english helps sometimes.
