Hacking N64 rom code editing

[lambofgod-laidto]

I was wondering if anybody could give me a link or tell me how to edit a n64 rom's code to enable saving when injected into a vc game. I've successfully injected a "Mega Man 64" game but it requires a save pack. I read somewhere it was possible to alter the game's code to disable the need for a save pack and allow it to save normally.

Any help is greatly appreciated.
