Hi everyone, I'm new to this community as well as ROM hacking in general.
So I've decided to start a ROM hack project recently, and I want to attempt to hack Super Smash Bros. for the N64 to add more characters. I've been considering adding Marth, Bowser, Robin, Ganondorf, Peach, Sonic, and a few others, although I'm not sure how many I can fit in the file.
Anyways, I've run into a problem, I can't find any good tools for a ROM hacking the N64 and I have no idea how to do it myself. When I attempt to search for tools that can help me mess around with N64 ROMs, I always end up finding Super Mario 64 exclusive tools, and I run into the same problem when searching for ROM hack tutorials for N64. I would greatly appreciate it if someone experienced with this whole thing could help me find what I'm looking for. Please and thankyou!
