Description: Timing is 4:58.14. I thought it was 4:58.13, but with a more accurate timing method, it was determined the time was a frame higher. This beats my previous time by a single frame! (1/60th of a second). My goal now is to get that 4:57 time! Leaderboard and Record Progression: http://smb-leaderboards.wikia.com/wik... __________________________________________________ Frequently Asked Questions: Q1: Isn't it faster to jump at the bottom of the flagpole? No, It is faster to jump at the top; When Mario drops off of the flagpole, he accelerates quicker to the castle, activating the timer earlier. Q2: You went through the piranha plants, why didn't you die? Flawed Hit detection makes it possible to jump through the piranha plants, with accurate timing. Q3: What did you do in level 4-2? It is a glitch. Jumping backwards into any object (In 4-2 - I did two of these) pushes Mario to the right side of the screen, the pipe and vine are close enough for the game to think I took the vine, saving time without a vine "cutscene". Q4: You went through the firebar in level 8-4 and did not die, why? Same as piranha plants. it just works. Poor hitbox detection. Q5: The first pipe in 8-4 you ran into the piranha plant and did not die, why? The piranha plant for some reason disappears as you approach it. Q6: Why did you do this run? To push the game to its limits. Speedrunning is fun. I wanted to see what time is the fastest I could manage. Q7: How did you jump off the side of that wall in 8-4? I did a walljump; simply catch Mario's foot in the 16th pixel of a block and jump on the exact frame Mario catches his foot. Q8: You took the wrong pipe to get to the water area in level 8-4? Yes, Going a certain distance past that pipe and then turning back tricks the game. That pipe is quicker, very slightly. Q9: Why didn't you fall into the gaps when you ran over them? You can run over gaps, you can even walk over them occasionally. Q10: How is this timed? Time starts from control of Mario and ends upon hitting the axe (SDA). Q11: Why slow down at the end of 8-3? I would have gotten fireworks, adding time to my run. If you hit the flagpole with a 243, you get 3 fireworks. Q12: What is the "21 frame rule?" The game is always running a 21 frame long (0.35 seconds) cycle from the moment you power on the NES. In each stage, you can only gain or lose time in increments of 21 frames. At the end of each stage, the game determines which frame rule cycle you are in and rounds the time to the beginning of the 21 frame cycle. The only stage where this doesn't apply is 8-4 since the time ends at Bowser's axe before the rule can take place. Example: 8-1 is one of the trickiest stages to speedrun because of the 'frame rule'. If you lose a single frame in the entire stage, you actually lose 21 frames. This is because of where the 'frame rules' happen to fall. When you play the stage perfectly, you are on the 1st frame of 21 in the best 'frame rule' possible. But once you lose a frame, you would now be on the 21st frame of the next 'frame rule,' and lose 21 frames. *Note The hitboxes in this game are weird. List of things you can get hit by in certain spots and not die: - Tops of piranha plants - Ends of firebars - Bowser's/Hammer Bros axes Note2 when mario moves downward, he takes priority over enemies
