So I think I finished the game after working for a few hours putting a saving card option and redealing option in.

You can opt to keep some or all of your cards. After pressing deal, it gives you new (random) cards and your final hand.

I think I solved a few bugs because I had the card numbers in the redealing part of the code backwards. It would help immensely to have them in the correct order. Because they weren't, it kept missing pairs.
Anyway, if you have Mednafen or a FlashBoy, please test the latest ROM and tell me what you think: http://www.atari2600land.com/casino/
Last night I put in a slot machine wheel turing sound effect. I thought it was awful quiet while the wheels were turning.
The next task for me is to test this on a real Virtual Boy.
