i just found a glitch to get a new 9 second wr in act 3 that would possible work in other acts

if you are interested you can watch the run + glitch here

its on flash version so its not actually possible on the required version

Glitches and innacuracies like these are why emulators are banned for runs I think. You can recognize emulators by the UI color, it's always red unlike the original release
