I captured video input with a simple python+QT script and emitted a button-press whenever the screen flashed. The best part was that the script didn't interfere with my controller - I could run around the area opening chests and battling random encounters, all the while getting closer to the 100-contiguous-dodges prize!
Sure - a memory editor would have had the same effect in 5% of the time - but this was _way_ more rewarding.
