I've been looking for compatible programs for the Treo 600, but I'm having trouble finding 5 way nav support. I thought that if I found programs that had OS5 and Tungsten 5 way nav support, they would also work on the Treo 600. So far that is not the case. What has everyone else found?

I'm particularly looking for a PacMan clone with no success. I have Yummi on my wife's Zire 71 which seems to work fine, but no such luck on the T600. Anyone no of a PacMan clone that supports 5 way nav on the Treo 600?
