Rockman.EXE was licensed by a "lesser known company" according to the
License Database on Animesuki... and there were 56 episodes in that series... I believe this show has already aired on TV in the States and also here in Canada...
The sequels are
Rockman.EXE Axess (licensed by 4kids) and
Rockman.EXE Stream...
If you need to know more about licensing... they have an explanation
here... and also...
AniDB is one of the better places to check for anime info...
