Hi everyone,

I'm a newbie in NES romhacking, but I already have some experience in Sonic hacking for the Genesis (Motorola 68k architecture).

I don't have a certain hack in mind, rather I want to to know if there's any way to produce a reassembleable ASM code of Megaman 2.

The Genesis doesn't have any mappers, and you can expand the ROM pretty easily, just by multiplying the available size and allocating it in the code (from what I know).

Megaman 2 seems to have the MMC1 mapper, and I would like to know how to -at least- expand the rom to maybe 512KB or 1MB, and for the most, as I said above to disassemble the game (I've seen some scripts for IDA Pro which could help with that).

The problem is that I no nothing about the mapper and bank system of the NES, and I hope to get to know more about it in the future.

Now about music. Porting music throughout Genesis games is really easy, since most of the majorly manufactured games use the SMPS engine (including Sonic 1 and Megaman: The Wily Wars). Though in the original Megaman 1 and 2 for the NES, the music engine seems to only have slight changes. (This page as a reference http://bisqwit.iki.fi/jutut/megamansource/).

It's almost identical to that of Mega Man 1. There are 12 bytes of optimizations.

An example to this could be the Mega Man Reloaded hack, which often appears in the header of the forum. It's a Megaman 1 hack which has music from MM2.

Anyway, I hope I can get some knowledge from this forum or try out some things I have in mind.

if you were starting a new hack from the beginning..
you could probably just use this to start your hack from.

Thanks for that, it should be pretty useful, even though it's for the Japanese version.

EDIT: Found this. Looks like it's just what I need.
