I found something that you might find amusing: non-tool-assisted videos of a skilled player playing Super Mario World Kaizo, also known as "A--hole Mario," a rather sadistic hack of Super Mario world.
I also found ROMs of these hacks, but no patches; if I can figure out how to extract the patches from the pre-patched ROMs I could upload them in case any of you want to try it. It would make for an amusing TAS demo, methinks.
WARNING: These videos give away the solutions to these levels.
