Default Re: Need some help with SMB hack.

Okay... keep in mind that my Romhacking knowlege is crude at best.

I beleive there are game-genie codes that affect this. Sno-bro wrote a very clear guide on howto convert GG hard code GG codes in a hex editor (plus you could easily modify the hex value to suit your needs)

This document probably has every SMB1 gg code imaginable.

Just isn't feasible. You'd need to code mapper use into the ROM.

You'd probably do best by hacking the fireworks code.

Probably a fairly non-painful way to do this, but i don't know what it is.

You don't.

Easiest thing would be to modify existing powerups.


Honestly, even if you were an expert hacker, for most of that stuff, I'm sure you'd have a much better time startning with SMB3, as it already implements a lot fo this stuff, plus, DarkDaihz has shown us how extensively one can alter the SMB3 core in Mario Adventure. In the end, I think the lack of Mapper use is what would ultimately kill a really ambituous project for SMB1.
