@Sireeni oon pelannu ihan pari vuotta tätä pelii, mut oli parin viikon grindi päällä, 4:57.660 -> 4:57.227 -> 4:56.944. :D

Okay good to know, it thought it was completely random, thanks.

@tryxdc Remember that you cannot buffer a jump in this game, if you try to jump even 1 frame too early mario will not jump. You HAVE to be grounded the frame you try to jump.

And while we're on this topic, can someone explain this.

@TetraSmashBox sub 4:54 is not possible, the last possible second barrier is 4:54 and a human perfect run is ~4:54.3.

Yea it's fine, apparently someone has even used a quitar hero guitar to do a speedrun so xbox 360 controller is okay.

Using the original video file i also get 2:33.930 using somewes.com

@KilleDragon Niftski has gotten it in a run and on pace.

Yes, you can use one of these FCEUX, Nestopia, Bizhawk, OpenEMU. i recommend Nestopia.

i'm just gonna say, it didn't work on nestopia for me, but it did work on fceux tho, i dunno why it doesn't work on nestopia.
