The following patch is available under a Creative Commons Attribution-NonCommercial 3.0 Unported (CC BY-NC-SA 3.0) license. In broad terms, this means:
TL;DR: Don't sell reproduction carts of this game translation; if you're going to retranslate the game, be sure to credit the team that created the original patch; and don't distribute patched versions of the game in any way, shape, or form - including prepatched roms AND reproduction carts.
Buy a flash cart instead of wasting your money on an expensive reproduction card that uses EEPROM chips which lose their data after a few years. Or, use a console-based or PC emulator. I'm totally fine with that. Please don't give your money to people who profit from stuff game translators do for free.

My second project, this game is a lot of fun. Imagine taking your favorite Konami characters and slapping them onto a game, and you'll have Wai Wai World 2. The game is fun, if a bit on the easy side. Most of the instructions needed to play are in the patch readme. Also, Demi translated part one as Konami World, so you may want to check that out too.
