@textfiles tbf if nintendo didn't want anyone to revive them, then they shouldn't kill them in the first place. The smart move would be to note the developers and outsource server maintenance to them for the remaining playerbase, like how dead MMOs get passed around and maintained, where nintendo pays the host a vastly reduced-from-new server bill. The publicity & goodwill alone is worth the cost.
Same for legacy console developing vs romhackers tbh.
