One of my standout memories is getting 100 super jumps for the first time in Super Mario RPG. I've done it several times since then, but I remember the first time was against Knife Guy. I had tried it a few times here and there, and had managed 30 (46 was my record at the time), and figured I'd give it another shot.
It started off normally, and I was counting in my head. When I got to 50, my brother got kind of a "holy shit" expression. As I was counting, and got up to around 80, I started to trip balls. My peripheral vision faded away, and everything turned white. Literally, it felt like the only thing I could see was the screen I was focused on, and it seemed to be floating. In the mid-80s, it occurred to me that I could actually make it, and I was praying that I could keep the rhythm going.
It may be in my head, but I could swear the timing for those jumps changes just a bit twice. But I digress.
I hit #100, and needless to say, Knife Guy died. I finished the fight, and moved on to Booster Hill. I did as well as I could there, but really, I just wanted to make it to the next save point, because the reset button was broken on our SNES (held in place with duct tape), and the system had a tendency to reset on its own (we called it 'blacking out'). If that happened and I lost my 100 jumps, I'd have been pissed.
Never happened, though. I made it to the save point in one piece, and my brother and I celebrated like assholes for the next little while. Thus, I got to enjoy the Super Suit to go with that nifty Attack Scarf.
Pointless trivia: Putting both of those on Mario gives you a higher speed rating than Culex, the fastest enemy in the game. When you start the fight, Mario gets a free shot, then he starts talking.
I've done it more since then (I became the designated "get me 100 jumps" guy), but the first time was easily the best.
