I have made a number of custom LSDJ kits:
Mario Paint: 29 samples from the SNES program spread across two kits.
Street Fighter 2: 17 samples in 6 kits, including the announcer's voice, insert credit, "Tiger Uppercut", "Sonic Boom" and of course "Hadouken!".
Street Fighter Alpha: 34 Samples in 4 kits, including cursor movement, game start, generic punches, kicks and blocks, and a kit each for Ryu (eg. "Shinkuu Hadouken!"), Ken (eg. "Shinryuken!"), Chun-Li (eg. "Gomene!") and Charlie (eg. "Too Easy!").
Star Trek: The Next Generation: A set of 5 samples in 2 kits, including some computer commands, a photon torpedo, a red alert and Picard's "Engage!".
