i've had a little prob that i think i some1 else on this board had too but not sure on which thread i saw it.
anyway, i've dowloaded a few games and they ended up in the app section of the phone and not the games section, and i found the problem, if you just add this line to the JAD file:
"Nokia-MIDlet-Category: Game"
(without the "")
that'll solve the prob.
sry if it's something abvious that every1 already knows, but i just wanted to help some guys who are now frustrated as i was.

Enjoy!
