I know these are ancient, but i remember some really annoying master system games....

The 1st was the second jungle stage on sonic 1.

YES!! That level was a bastard!! I never was able to beat that level by myself, I had to get my father to help me -_-

if u think level 3 is hard on shinobi, wait untill u get further because that game just gets insanely harder, its da only game dat ive havnt beaten yet and ive had it for about a year already. i think i stopped at level 5 or 6 dont remember.

Shinobe was my kind of game, I loved it. It was exactly like the old mega drive games I loved so much, unfortunately it could have been longer, I beat it in two days...................................

I played revenge of shinobi. And after years of trying i actually saved the girl before she got smashed.

Another lvl is the last level in shinobi for ps2. I wanted to rip my hair out. so insted i sold the game that will teach them!!!

every level in Contra-Shattered soldier,, playing through the game is not that hard, but to see the real ending you have to beat the game perfect(loose not one live, shoot everything that adds to the percentage counter, thats the tricky part)

and lets not forget the final level of Viewtiful Joe, no comments on that one.

The later challenges in Amped get me. They're just so annyoing, the controls are so unfluid so you can't rack up the big points like in SSX 3.

Oh, and guyverfanatic, Cam's car is bulletproof! Meaning it won't blow up! If you havn't already finished the mission, get out of your car and go to the last part of the race, the bridge. Wait the there with a sniper rifle and snipe him when he's about to finish the race. Take the car, put it in a garage (other than the one in Downtown, where stuff kinda goes missing from time to time) and beat teh wuss the next time^^

Well, Right now I'm playing MegaMan Battle Network 4: Red Sun, and I can't get past the first guy in the second tournament....

The boss fight on Xenogears against Opiomorph was pretty difficult.

The Kabel Ruins in Legaia 2 the puzzles there make me want to scream.

I am currently playing Alter Echo. I am at the part in the game where I fight a copy of Paavo. >_

*spoilers to Final Fantasy X*

My best friend has been stuck on the boss that you fighto on top of Cid's ship (it's not Sin it's the flying serpent monster). He's been trying to beat it for about four months or so now. The only time he fights it is when he's over at my house and we've been busy over the summer so he couldn't get a chance to play it for a while. Last time he was over he made his characters level up (I know they don't actually level up in this one but you know what I mean). During his latest battle (3rd time while he was over that day) his mom came and picked him up and thus leaving me to finish the battle. I almost had the sucker he was down to 5000 HP but he beat me in the end. Now I've been training his characters for him non stop (he said I could so he doesn't mind) I think I'm just about as tired of watching him loose to this boss as he is loosing. I'm quite sure the problem isn't his level's (he's put them through many recenstions of training before.) I think he lacks skill, but he'll learn eventually (and I'll make them stronger)

BEAT HIM RYAN!

Onimusha 3

Critical Training Advanced mode

This part of Onimusha drives me insane not only do you have to face the toughest non-boss monsters in the game but you also have to face them two at a a time killing them with nothing less than a critical. This level is unforgiving.

Currently playing Blood Omen 2. The first boss is so damn annoying! He keeps jumping out of the way when I attack him! I can hardly hurt him to boot....
