Are there any cheats for sonic adventure DX

Yes there is if it is on game-cube you can use AR action replay or if it is on PC use cheat engines there are also many glitches like take sonic into eggman's building in mystic ruins and go to the middle of where you find metal sonic and silver-sonic v.2 and then use the homing attack until you are behind the wall walk over to a capsule and you can go through it hope this helped
