Super Mario World beaten in 10 A/B presses

[insert parallel universe joke here] Not much to say. All of these strats are known in some form or another, I just put them all together. Tool-assisted, but not fast at all. Jump count by stage: YI2: 1 YI3: 1 YI4: 1 1C: 2 DP1: 0 DS1: 0 DSH: 1 SW1: 1 SW2: 0 SW3: 0 SW4: 1 FD: 2
