Lol whole of cheats in plain text in the game.
I don't know what they do, only the last one : debug menus.
Enter them on the main screen (with the 'NEW GAME','LOAD GAME'... text). RS and LS are R trigger and L trigger btw (I guess S actually stands for Shoulder). You'll hear a sound if they are entered correctly :
#1 : L-R-L-R-U-D-U-D-RS-LS
#2 : LS-RS-U-U-D-D-L-R-L-R
#3 : L-L-L-R-R-R-U-U-D-D-D-D
#4 : RS-RS-R-R-R-U-LS-LS
#5 1.000.000 chips : START-R-U-L-D-SELECT-LS-RS
#6 3.000.000 chips : START-START-D-D-L-L-U-U-SELECT
#7 Unlocks 1 bonus game : D-D-U-D-D-RS-L
#8 Unlocks 1 bonus game: U-U-D-LS-LS-RS-RS
#9 Debug Menus : U-L-D-R-U-L-D-R-U-L-D-R-RS-LS-START-SELECT
Edit :
#5 and #6 can be both used (it'll then give you 4 millions chips).
#7 and #8 unlock some games, but they can't be played right away ?
Edit2 :
The Debug menu has some cheats menu, which can open all levels, all characters, all extras, all minikits, give you 100.000.000 money, and skip activation (?), making all the other 'cheats' I listed kinda useless...
And the 'extras' open things like regeneration, infinite torpedoes, invicibility, score x10...
For all those that have some broken keys on their DS :
