Kart for SMK, and Seven for FF7.
I don't know if you already knew this glitch, but I found a new one this evening at Nibelheim, during Cloud's past (saves 20-25 seconds) :
You can save about 20-25 seconds by skipping the picture scene. The idea is talking to the photographer at the same time you're trying to go into the Nibelheim's Mansion. You'll activate 2 dialogs at the same time (the photographer when you're talking to him, and Sephiroth who says it's not the moment to go in Nibelheim's Mansion). With this glitch, you can move Cloud and directly leave Nibelheim without the picture's scene.
You can try the glitch several times until it works. Of course, do it as fast as possible, as it doesn't save a lot of time. By the way, it's not very hard to do.
