Game Genie or Action Replay
Ive no idea I rarely see them online. I usually have a less success rate when my opponent reads my teleports and jumps away. Id also try fuzzy blocking when at close range as Raidens back+3,1,2 and 3,3,4 have lows and mid attacks in them meaning they can break your low blocks and hit overhead etc which can be hard to judge which height to block.

(An thread on it and i recommend the site in general for play tips and strategies. The guides and tournament play videos have helped my game alot i recommend)
Im not awesome at the game but im practiced, i would probably take on Raidens and study what they do and why your loosing. I dont think there is one set way to beat human foes as there would be no point in playing the game, but there are things players will always attempt to do. Id try your best to try and learn what they are doing and what tools your character has to beat them.
Is there any EX specials you can do with armor that you can use? Try blocking? Dash back when he teleports?
I would just practice dude. If you keep loosing at a Raiden player dont get mad and quit, keep playing him until you learn what hes doing and what your doing wrong. Chances are you will end up beating him a few times.
