I have the Japanese version of this game, it's called Rune 2 in Japan. Why only US and Pal on the Leaderboards, the JP Version is legit

The Japanese version is on the Leaderboards! In fact, both I and 7thArmstrong have runs up for it. It's on the top banner under "Rune II Any%"

You planning on doing a run for Rune II!? :D
