Jinpachi is not hard at all, just has two extremely cheap moves, the stomp that paralyzes you and the fireball that takes off all of your health. If you rush him and get at him before he can do either one, he's dead in about 7 seconds. I double perfect him with Steve quite regularly

SNK vs. Capcom SVC Chaos has totally fanny bosses, as already mentioned. Orichi Iori gave me way more trouble than Violent Ken, though. Even one of the normal characters is a total pain in the arse (can't remember what his name is, SNK guy who stands back and just throws those screen filling tornadoes all over the place. I smurfign hate him )
