Here's my list of cheats for each card. I'm actually missing 565. I haven't beaten the game yet, maybe its enabled after a special event? I checked the guide it seems to be from the MGA2 deck. If anyone could help it'd be nice.
Locating the values for available cards was easy, enabling them was a nightmare. I had to literally search for each card by 'hand' with a hexedit. In order for the cheats to work you must enable them before loading your save file. Sorry that's the only drawback. Enjoy
By the way if there are any repeating mistakes, feel free to enlighten me. It'll be easier for me to correct any mistakes since I wrote an application to repeat codes.
