STK 0.6.2 is very nostalgic for me, so lately I've been trying to find more addons for it, which is a bit hard since the pre-late-2009 forum crashed. But I did manage to find this hidden gem on a German SuperTuxKart site.

Looks great! But as far as I remember, STK 0.6 was really hard to play. The controls were unforgiving and colliding with an AI kart almost always sent you off the track.
