You have to search around literally everywhere; on the net (talk to random navis), in signs, bushes, etc. Just go around and search and eventually you'll get 50.
I found 51 or 52 points 1 time when i was searching really hard on hard and very hard difficulty.
no you can only link megaman games together if it is the same number like megaman battle network 3 blue to megaman battle network 3 white
Well.. you fight the purple navi inside Draky and you have to talk to people in electown to get a couple of points.
