Valve then forwarded us the statement from Nintendo's lawyers, and told us that we had to come to an agreement with Nintendo in order to release on Steam.
We all know Nintendo is a bitch and there's nothing illegal in emulators, but Valve's stance looks reasonable to me, it would be serious damage to Steam if they were involved in ~~legal~~ litigation.
