I was thinking, why doesn't GBAtemp get ROMs that are older then 50 years? The copyright doesn't matter if its older then 50 years, right? So wouldn't hosting ROMs that are older then 50 years be legal?
Also that'd be a terrible idea -> you'd have people confused as to what ROM links they could post 'n' stuff.
Anyway there's already tons of websites that host those, it'd be pointless to start adding them out-of-the-blue.
