Mega Man 3 Improvement

Hack of Mega Man 3


This is an improvement patch for Mega Man III/Rockman 3. It has many improvements to the game + MANY bugfixes that existed originally in MM3.

Anyone is free to use this for their own Mega/Rock 3 hacks, and any new ones in the future.

Please only use the appropriate patch depending on what ROM your using. The megaman3 patch is only for the English version and the rockman3 is only for the Japanese ROM.

The author will not list all the changes here, they are already listed in the readme. A youtube video was uploaded also to demonstrate many of the changes. Please see the “Video Comments.txt” for the link to the youtube video and to use as a guide to note the changes you’ll see demonstrated.

An ASM file was used from the Japanese ROM hacker named Puresabe, known best for Rockman 4 MI (Minus Infinity). It implements some gameplay physics mods that he presented to me. NOTE: It already has been applied to both English and Japanese versions of the patch.

Absolutely The Definitive Version of Megaman 3

Reviewed By: Eldrethor on 17 Feb 2018

For years, I’ve always found Megaman 3 enjoyable on its own, but this hack provides such a huge quality of life improvement that I could never go back to the original. Being able switch weapons on the fly makes for much smoother play, and the new opening screens fit seamlessly into the game. Being able to freely revisit and exit beaten stages is also a welcome change, as are the handful of bug fixes and additions of unused sounds and graphics.

This improvement hack pushes the game’s build state to what is probably the most complete it will ever be, and it does so much without detracting a single ounce from the overall look and feel of the original. Hats off to kuja killer for what is easily a 10/10 rom hack.
