Essentials

  • Emulator used: FCEUX 2.2.3
  • Aims for fastest time
  • Takes damage to save time

Run overview

I improved the previous run by 1436 frames (~24 seconds), due to a wallzipping trick, high jump, and various optimization.
I used a HUD script to optimize. If you want to know about memory addresses, check it.
This run is based on excellent previous runs. I appreciate the authors.

Tricks

Wallzipping

You can zip into some walls, but the wall must be two vertical contiguous blocks, and you can zip only from right side of walls. This trick is posted by Tarbash, thank you!

High jump

You can jump 5 pixels higher when you press A and SELECT simultaneously. It increases initial y-speed.

Tips

This game is hard to TAS, due to its strange mechanics and many lags. So I itemize some tips:
  • To reduce lags, minimize the number of objects in screen as possible.
  • Sometimes you had better not kill enemy. When screen is filled with objects, some succeeding enemies may not appear.
  • Subpixels do not consider sign. This is the reason why the game does not calculate position correctly when you move left or up.
  • You can change your weapon with SELECT while screen transition, and it often affects the amount of lags before next screen.
  • If you attack at the moment you touch ladders, your velocity is remained for a while.
  • When an enemy is spawned, its subpixel is not initialized. So, movement of enemies depends upon previously spawned enemies. If you need to manipulate it, try killing some other enemy (which has the same index in object list) at different timings.
  • Driving stages are mysterious. Some obstacles occasionally disappear. And the amount of lags sometimes increase for unknown reason.

Reference

  • Maps (thanks to Will Mallia)

Nach: Judging.

Nach: Replacing submission with improvement from author.

Nach: Nice speedy run, improving on the time of the previous. Great audience response. Accepting as improvement to existing run.

I could not download your image directly, but I could view the image by pasting your URL to imgur.com: Btw, I'm Japanese :P Anyway, nice thing. If you post your movie file to the game thread, it will definitely be helpful for future improvement.
