Want the roulette exclusive items like the rages but hate to look forward the normal roulette and fail?
Here's a vid trick. (Thanx D_C for the find).
The transcription goes as follows:
1) Go to arcade or ghost mode and fight until you get the flashing bar over your name (roulette chance).
2) when you got the roulette chance, pause the game and quit.
3) go back to Ghost Mode and get your fight. Win or lose, you'll have your chance.
4) if you got the LUCKY entry, try super roulette, you might have more chances to get roulette and the item.
5) If not, press the PS button and leave the game. and re-enter again.
6) it's kinda time consuming but better than scavenge for random roulette chances, when you restart your game, it's saved with your roulette chance.
It works perfectly fine in all the home console and the PSP ports. It's still a fucking bitch to get, though.
