Card Game [Model DMG-CGA]

Game select menu cheats:
All cheats must be entered at the game select menu in 1P mode. Hold Select, then enter Right, Down, Left, Up, Down (the common part of all cheats). Do not release Select, then complete the code with one of the sequences from the table below. Each cheat upon completing the D-Pad buttons input will point to the corresponding game, so you automatically will start a corresponding game, which affects the code in question. Note, that cheats may be combined and will work until you reset the console.
Right, Start - Ending
Right, Up, Left, Start - In a Poker game, now you can do discarding of your cards up to 5 times in row per turn instead of only one discard. Hold Select before completing the discard process to skip to the next turn instantly.
Right, Up, Start - In a Black Jack game doubles any pay-out even if you has a draw.
Start - In an U.S.A game, when players hand has only one card, code prevents from SKIP, so you will have one card always during the CPUs turns.
