Mega Man 9 is relatively new, so if Capcom releases a C&D letter, the patch will be removed. I also advise anyone who plays the patch to support the official release. I in no way condone piracy and the project's purpose is not for financial gain.
I got a new project on my hands.
Here's the latest patch. Apply the patch to the American version of Mega Man 3.
Some various levels.
