Econo v1 Readme

Econo is an SMB3 Kaizo Hack. I aimed for a difficulty that can roughly be described as "intermediate." I made it using a USA Rev1 version of SMB3, and I cannot guarantee that it works with other versions. You can watch the trailer here, but it does contain spoilers (of course): https://www.youtube.com/watch?v=RSv4RPyHEEo.

This hack is loosely inspired by and dedicated to the music of the Minutemen. I hope you enjoy it.

Special thanks to the following people who directly contributed to the hack. A full attribution of patches/asm is in the "spoilers" section at the bottom of this document.

If you have any questions about making SMB3 hacks or about any of the patches/asm used in the hack, feel free to reach out. And if you encounter any trolls, cheap deaths, or jank, I don't know how they got there.
