Explanation in the video. Feel free to ask anything if you need/want.

@a_xxEzraBxxx_b It's just a safer way to do it, no time save intended.

If you press left at the right time, you'll clip more into the block. If you mess up by pressing left a little earlier than you should, you still can do a 2-3 frame walljump. Since the video was recorded at 30fps, the first walljump was at the 2nd frame (4th frame at 60fps), and the second one was at the 3rd frame (6th frame at 60fps). I don't recommend you to delay your walljump too much, try to do it as fast as you can because If you did a bad clip, you still have the chance to do the 2-3 frame walljump. This is faster than climbing up the invisible coin block perfectly (with/without a headbump). I get the walljump most of the times with this method, way more times than with the 2 frame one. Feel free to ask anything if you want.

Video for comparison:

Since I don't have a NES, neither a PC, the only thing that I can play on is my PS2. The FCEUMM-PS2 emulator is a port of the PC emulator FCEUX. It works perfectly with SMB1, SMB2-J etc. The only game that doesn't work properly is Mike Tyson's Punch Out, but the rest of the games work 100% well. If this isn't enough info, what would be the procedure to verify this emulator to be accepted at this leaderboard?

@Mars02 it isn't necessarily on the first pixel of the block. Sometimes I hit the block a bit higher and I still get the headbump.

How to do it: Do a backwards jump into the left corner of the invisible coin block, release right when you hit it, then do a frame-perfect jump to preserve your running speed. Start holding right again when Mario reached the middle of the block. Try to adjust your jump height to land on the block as soon as possible, then jump to the pipe. If you kept running speed correctly, you should exit the room with a 365 on the timer (366 if you did a fast acceleration on the first or the second room). This is enough to get the any% glitchless WR down to 5:03.5xx.

Sorry about the bad quality recording. I can't change the shutter speed of my camera :(

Is there any aproved android emulator for speedrunning?

Ok. Thanks for the attention.

There's an app called GameGuardian, that can speedhack the games, but only on rooted devices. So, is possible add 2 new categories for these speeds?

So, who controls the moderation?

Thanks :) . One question: can I moderate all the 3 GDs? Some moderators don't have all the time to moderate, and I can moderate every day. I know how GD works and I can see discrepancies easily.

Some people have a better PC to play gd, but some people have a mobile to play GD, and the loading time can be variable, like in the Gauntlets, the loading time is slower than high end PCs. So, is possible to fix this problem killing the fade loading time in the runs?

For android, is possible use GGuardian for speedhax?
