Mega Man 3 Improvement

Hack of Mega Man 3

Description:

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.

This is nice

Reviewed By: InAnotherCastle on 14 Jun 2021

I don’t have enough of a history with Mega Man 3 to have an opinion about all the changes here. But what I’ve noticed is all good. Especially the slowdown fixes. This hack works well on real hardware - I’ve tested it on an Everdrive and made a repro cartridge. Also recommended is combining this with the refill hack!
