Isn't it nice when other people inspire and motivate you? Thanks to infidelity, I was inspired and motivated to convert Mega Man to Mapper 5: MMC5, and I did it all by myself!

This is my first Mapper 5 conversion, and it was successful!



Patch and readme included inside the zip file.

Download

This patch is for the English version, Mega Man, not the Japanese version, Rock Man.

EDIT - To anyone who already downloaded it, I deleted the zip file and re-uploaded it, because I forgot to include in the readme that this ROM was only tested to work on FCEUX 2.2.2.

Patch MMC5 Mapper works on JP version of Rockman 1.
US version of Mega Man 1 MMC5 Mapper works on BizHawk 1.8.4 (NesHawk Mode not QuickNES Mode).

RetroRain's Mega Man Extended Edition (Upgrade MMC3) + SRAM support not work Rockman 1

EDIT: Can't wait for Mega Man 2 MMC5 Edition + JP version support.

Sweet. So with the proper modifications to the sound engine I should be able to upgrade the music, right?

Good job! Keep up the good work.

Rockman 1 is the Japanese counterpart of Megaman 1. Therefore, the absolute addresses and other code/data would be located in different places apart from the NTSC Megaman 1. I have the feeling that you don't really understand what this means but basically, when you assemble (what every game developer did back in the 80's), code/data are assembled according to the number of bytes used for each PRG bank. The assembler would take care of addressing absolutes as well as big/little Endian. When patches are made, they are to be applied to a specific work. --ShaneM

I don't see why not.

A MMC5 version of Megaman 2 is on my to-do list.

Thank you ShaneM!

Although I do plan on doing more MMC5 conversions and getting back into ROM hacking (I realized I should've kept SMB The Wrath of Bowser a ROM hack, and I might make Megaman Recall a ROM hack of MM2), right now I can't do anything more on the computer because my eye-strain/head-pain is really really bad, and I need to take a break from the computer. It really sucks when I have to put my passion on hold because of health reasons. I'm concerned that I may have to give up my computer hobbies altogether because of this health problem, but I do have a list of projects that I want to do. We'll see what happens.

Excellent work! :-D Converting is a lot of fun, especially when the end result works, lol!

Thanks infidelity!

I wanted to do a mapper 5 conversion a while ago, but I was turned off by how many registers there were. There were so many mapper registers to setup and write to, but then I realized that you don't have to set up every register, and you just have to have a little bit of patience and go slowly. It wasn't as hard as I thought it would be. If you didn't release your SMB3 conversion, I probably wouldn't have done this. It's really cool when other people inspire you.

I used the article at wiki.nesdev.com to do the conversion. I recommend it to anyone wanting to do MMC5 conversions.

And now that I've done my first MMC5 conversion, I don't see any reason to go back to older mappers.

Again, it's good to see you around and that you're still working on stuff.
