Author's comments and explanations:
Alex Kidd in the Enchanted Castle improved by about 79 seconds (4738 frames).

Thanks to Foda for the previous movie, which helped me a lot! Foda also gave me feedback that helped improving this movie.

There are 11 levels in the game. These are the improvements:

My route for the final level abuses two new tricks:

  1. The bike can be used to gain enough speed so that you get stuck in a wall. Then you can ascend by jumping inside the wall. This trick is used four times for shortcuts.
  2. If you get damaged when you are using the bike or the helicopter, you sometimes get warped upwards the height of approxximately 7 blocks. This trick is used once by equipping the helicopter, touching an enemy and warping to the screen that is located above.

Here are useful RAM addresses:

Alex's X-axis sub-pixel position 00FFD01A
Boss HP 00FFE126

I'm sure that some sub-pixel optimization is possible in the final level (and maybe in level 9), but I'm not used to it, so I can't understand how to do it perfectly. So go ahead and improve the movie further, if you can handle the sub-pixel world. I would enjoy seeing any improvements to this. :)

The movie attributes are the same:


NesVideoAgent: Hi! I am a robot. I took a few screenshots of this movie and placed them here. I'm not sure I got the right ROM though. (I tried Alex Kidd in the Enchanted Castle (U) [!].gen, which was the closest match to what you wrote.) Well, here goes! Feel free to clean up the list.

Bisqwit: Replaced file with a new provided by the author. Apparently, it is 21 frames faster now.
adelikat: Accepting for publication as an improvement to the published movie.
