Enter Xka Shack. This SMW hack was made entirely through patches and xkas, and features semi-randomized levels. For this reason, it has proven difficult to TAS. But a user by the name of DarkMoon determined how to manipulate the RNG to get the best "randomized" levels and uses this to beat the entire game, 107%, in just under 3:30.
