He has 6 for Card Duels (Impulse [3-Card Duel], Dark Impulse [3-Card Duel in Dark Mode], Maelstrom [5-Card Duel], Dark Maelstrom [5-Card Duel in Dark Mode], Barrage [7-Card Duel], and Dark Barrage [7-Card Duel in Dark Mode]), 4 with King Mickey (MM Miracle LV1, MM Miracle LV2, Holy Burst, and Inverse Burst), Dark Break, Dark Firaga, and Dark Aura...he gets all of those after fighting Ansem for the first time, after the first Reverse/Rebirth world, Hollow Bastion. Is there really a point in hacking it, when you get them after the first world anyway?
Don't think this'll help much, but I tested the jokered Enemy Cards Code, it worked, but it doesn't give you any Enemy Cards other than Heartless (no Boss or Organization Cards, in other words)...
Well, I think I recall EvilMan saying something about Jokering the code if it doesn't work for you, see if that helps. The code for Max CP...it depends on what you want your CP to be. You put in the hexadecimal value for the amount of CP you want.
For example...
9999 CP:
2060D2A4 0000270F
270F is the hexadecimal value for 9999.
999 CP:
2060D2A4 000003E7
3E7 is the hexadecimal value for 999.
About the All Enemy Cards code, I tried it and it froze for me, but remember to Joker the code if it doesn't work for you. I tried it, and it was fixed.
