Has anyone taken a look at the new function? https://www.libretro.com/index.php/retroarch-1-7-2-released/

With that cores like genesis plus and higan, which are cycle accurate, should be exactly the same as the real hardware in terms of accuracy of emulation and lag input. I think we should encourage the use of this so more people can speedrun in equal grounds if they don't have access to real consoles and good crts.

The only caveat, I think, is that we should determine how much input lag the real console has to set the standard for the emulator. I know from my speedrun (Bare Knuckle 3) that it has 1 frame of input lag, but I'm not sure if that is from the game itself (like SMB has 2 frames of input lag as shown in the video of the article), or from the emulator. I don't want to give myself any kind of edge by using emulator, I want it to be fair for everybody.

What are your thoughts everyone?

Thanks!

So long as it's not running faster than console, I don't see the issue, other than setting it so you have even less input lag than console
