What you're looking for... is hard to pinpoint exactly what you want without knowing what game it is. Most games compress their files, most of those games can be decompressed with gedecompressor, aka Universal N64 Compressor. Then you'd need to figure out what file's what, as if it isn't Zelda, you most probably don't have filenames. Then you can look through the files with N64Rip which, as you will see, would need you to go through the same file with almost every format that it supports. Then repeat for any other file in the ROM that the decompressor spits out.
Other than that, have fun!
