Played on WabbitEmu. There seems to be an issue, at least for me, regarding speed. My first attempts were all on the standard mode of the emulator (that shows the full calculator) and the game would run a little bit slower than what's supposed to.

The option I changed is "Enable skin", this only shows the game screen as it's shown in the video. By doing this the game suddenly started running a bit more faster. I even doubt that the game might be running slightly faster than Plank's WR, but I'm not sure and I don't know how to test it. But then again, with the "skin enabled" the game was slower than said WR, so it's an unfair advantage on both sides.

After a little bit more testing I realized that the bigger the screen is, the slower the game runs, so if anybody wants to attempt a run in the future, just make the screen as tiny as possible. It shouldn't be an issue right now, but if somehow the times get more optimized then there should be more testing done so that all runs can possibly be at the same speed.
