Hey Guys I would like to mention something that I consider very important to the speedrunning community of SMB1 and SMB2J.

It all started off right here.

If you notice keenly, you will see that FCEUX is lagging behind Nestopia despite starting at the same time. ( I enabled Background Input in FCEUX and mapped all the keys to be same in both the emulators.) So I got Curious and used the built in lag counter in FCEUX to see what was the issue. And This is what I found.

Everytime a level is started or a pipe is entered or exited or a vine is climbed a single frame of lag is added. If this is some other game this would be insufficient. But in SMB1 and SMB2J due to the framerule system this is a pretty big deal. The issue is that this adds up over the course of a run. You lose around 0.1 seconds for MWE, 0.2 seconds for Any% and more than half a second for Warpless.(These calculations are done assuming that you don't die.) This can affect runs that get calculated based on milliseconds. So there should be a system of calculation that is capable of eliminating this lag or people should avoid using FCEUX altogether.

The versions of emulators are FCEUX : 2.2.3. Nestopia : 1.40

Well, I got bored and was playing with two windows(I enabled BackGround Input in FCEUX). At that time I noticed that in FCEUX, the game scrolled and stopped one block short in the TurnAround Room while in Nestopia the room scrolled a bit further. Can someone explain it to me??????

Hey Guys,I recently got back into speedrunning and idk why, but FCEUX lags a lot. So I decided to use Nestopia and it works fine.But the colors on FCEUX were a lot better so I tried using the FCEUX palette on Nestopia and it works fine. So the question is, is it fine to use a custom color palette????

Hello Guys.I just began speedrunning a few days back.And I sucked at getting the 1-2 clip.So I discovered the "Bump Strat".It will be helpful for beginners.

Here is the run that I did with this strat.
