Good day,

The Switch version coming from Nintendo Switch Online (NSO) is allowed as it's the original rom that is being fed to the Switch.

However, the US and JP versions from Kunio Kun: The World Classics Collection are not allowed, as these have got major QoL improvements implemented in them, most notably with system lag. Therefore, it would not be on equal footing with the original game.

Should runs of this version ever be made, we will add a leaderboard for it.

[EDIT: It appears that there doesn't seem to be any interest from the playerbase for this version. Therefore, this version will be removed from the leaderboards until there is significant interest. However, until then, the ARC Systemworks versions will NOT be eligible on the current leaderboards.]
