Need cheats for jump ultimate stars

if I'm using a n-card clone to play JUS, is it possible I can get cheats? If so, how? Thanks for any help.

Should use AR codes. Try seeing the official site for more info. AR codes at http://www.codejunkies.com/

Do I need to buy an AR machine? Or is there some way I can put AR on my flashcart?

See if there's some sort of cheat database file amongst your firmware, dat, txt, xml etc.

do you know if an n card clone flashcart has cheats? I checked it it did have a dat file.

Okay, see my "How to Add Cheats To R4" tutorial in the Tutorials section of this Forum, it should give you an insight on how to add them, that editor should work with your .dat file too.

but if its only for r4, it won't work for n card right?

Well that's the whole point of it, not every exact step in it should be followed for your flashcart, but you should try getting that database editor, and try to edit your .dat file.

i advise you not to use any cheats for JUS unless youre really stuck
youll just waste the excellent gameplay of JUS if youll cheat your way through
