We have decided to split the leaderboards into "original version" and "anniversary collection". Anniversary collection is very different (way Faster) and therefore not comparable with the other allowed systems/emulators. The Anniversary Collection however is an official release and it is also good, so we think the right thing to do was splitting the boards, so runners can still submit their AC runs and compare them others. All AC releases are very accurate compared to each other so AC runs are allowed on Nintendo Switch, PC, Playstation 4 and Xbox one. Cheers! and Attack Aggressively!
