Title: The Hummer - rom extracted and FULLY ported to MMC3
Post by: 19rsn007 on April 26, 2015, 02:17:20 am
Hey People!

I don't know if you guys know about the somari hack called THE HUMMER.
It was released on the very rare Super New Year Cart 15-in-1 from Hummer Team, which runs a weird mapper (mapper 45)
This mapper is an MMC3 clone, but with some weird cards up it's sleeve.

It was also released on some plug and play NOAC based consoles, but every level had a menu entry as a separate game.

A few hours (and notes) of work later, I managed to extract the game from the 15-in-1 cart, and make it run on a standard mapper 4 (MMC3)

Look at the youtube video below:

Congrats!  Nice job, was it difficult?  I don't know my way around this kind of coding, but thanks for the video.  Does it run on real hardware?


So, I guess the question we're going to ask is - could you convert the Super Mario World full ROM to MMC3 as well?!  I know they're different mappers (SMW is 90) but it got me thinking :D

Will you be sharing your hack? I'd enjoy a chance to try this on my Everdrive.

It was a little hard.
The mapper the multicart was using, was acting a lot like MMC3, but I had to do some adjustments to the game itself.
I have no way on testing it on real hardware right now (working on it).

Mario World is a whole different ball game!
It uses even more complex tricks and can not be ported to MMC3.
It has some weird ways of mirroring, which makes it possible to scroll smoothly horizontally and vertically at the same time and the bankswitching used in there is being examined.
I was checking into that mapper 90 to see if I could somehow port it to another official mapper.....to be continued.

In the meantime, I tested the rom in Nintendulator, with a speaker attached to the headphone jack of the laptop
Here's a video of the thing running:

Good work you should upload it for us everdrive owners to test on real hardware for u.
Looks like a really cool sonic clone.

Hery people,

It has been a while, but i finally took the time to test this thing on a real MMC3 board.
