How are you storing the dealt cards? 2 bytes per suit, where each bit represents a card? 1 for dealt, and 0 for being still in the deck perhaps?

Since this is a Virtual Boy game, I have no idea how many bytes are taking up what.

I am using C, so I can tell you that I am using Suitnumber[0]-[4] for the suits and Cardnumber[0]-[4] for the types of cards (A-K).

One efficient way to shuffle a deck of cards:

for i = 1 to 52

j = random(52) + 1

c = deck

deck = deck[j]

deck[j] = c

next i

Thanks, but the VB has no random number generator.

You can always create your own PRNG. The shortest one would be a LFSR, and there are other concepts if you don't have access to bit manipulation. Actually a PRNG should be part of your library, whether it is available as a ROM routine or your own code.

You will need one. How else do you plan to shuffle the cards?
