Is it legal

From AU, 1 post

I was looking at heading snes rom section at http://www.freewarelive.com. I have setup the atari and commodore sections because they went belly up and are not going to track me down anytime soon. But would it be legal to post...



SNES Roms?

Sega Roms? (Sega are no longer dealing in consoles)

Mame Roms?



or is it a trivial issue?



Thanks...
