Actually I only upload the ones where I win, because I think the loosing ones will be a waste of time to watch and it will leave you wondering if that matchup is possible to win with that character or not. I didn't loosing in the Sagat and Juli video, but I lost a lot, when trying to make the Karin video, since she doesn't have an uppercut and while that video is suppose to be long, the loosing fights will make the video even longer. You will end up seeing me restarting the same matchup that I lost over and over, until I win and that wouldn't be fun to watch. Some of the moves, I have them set to one button, to make it RDB easier. The PSP controls are difficult, for fighting games. The difficulty is level 8. You can see it on the bottom right, on the character select screen.
Having an uppercut doesn't automatically mean you'll win every fight easily, it just means you have a better chance at winning. There's actually some matchups that are difficult, despite your uppercut and specials being set to one button. That's how hard RDB battle is, on level 8.
