The N64 roms are in .7z and when extracted give you sometime over 100MB of roms. Most of them don't even work, so I'm just saying post the 64 file that works best like before.
We don't have time to test them all and find out which work and which don't. If you know which file in an archive works, you could post the filename in the game comments.
Usually you can figure it out by the tags, there's a tutorial in the tutorial section on what they mean.
