I remember always being told not to use it because it lags the game more, and at least adelikat has told me he doesn’t understand what it does and suggested not to use it. But may it actually be more accurate? xy2_ posted that the DSBot synced better with it enabled, but didn’t provide any proof or explained any better than that. I think Masterjun challenged his post, but again I don’t think xy2_ replied. Regardless, I think I may have proof that at least for Mega Man ZX, having it enabled more accurately replicates the real console. Look at the RTA leaderboard: http://jokaah.com/mmrta/index.php?game=29. Everyone playing on emulator in the top 5 has it disabled, notice how their IGT is slower than the console WR, but their RTA is faster (relatively). I think it’s about time we put an end to this debate. Which is the truth? I think it was Nitsuja who implemented Advanced Bus-Level Timing, and on that note… where has he disappeared to? Does anyone know?

Well, enabling the option fixes audio bugs in the DS Golden Sun game (Dark Dawn or whatever).

The reason I believed Advanced Bus-Level Timing was more accurate was when doing some input for the Brain Age run: I had made most of the input with it on, but forgot to turn it on for one segment, which completely desynced that segment of the run on an actual console, due to there being less lag without Advanced Bus-Level Timing. The best way you can truthfully compare these would be to make one or multiple comparaisions with thee same segments of the same game; one on hardware, one without Advanced Bus-Level Timing, and one with. See what is more faithful to hardware.

Link to video Keeping entering the same door might be a good way to test the accuracy of lags.

Or just leaving a game running for 10 minutes or so, also works reasonably well.
