When switching games on these machines i noticed they each have different previous hands dealt.Does each game have a seperate rng or chip?Also  it says on the machine that this machine uses one 52 card deck.How can this be if you switch from deuces wild to joker poker there are 53 cards used in joker poker.The deuces wild game has the deuces marked wild so if you change to jacks or better the deuces in jacks or better are not marked wild.So they cant use the same chip for all 6 or 7 different games can they?and they cant use the same 52 card deck for all 6 or 7 different games can they?

Each game program has a different set of internal data but share several common subroutines. The RNG is probably one of these share programs. Think of managing two (or more) checking accounts with separate log books but using a single calcuator to do all your accounts computations.
 
Internal data would include the last hands played, card images, etc. I realize this is a rather short answer and the programmers out there will understand, but if this is too cryptic let me know and I will go into more detail.

Note that the "Jokers" games will have more than 52 "cards" in the virtual deck.  But, that's really just changing the table to 54 occurrences and adding 2 more values to represent the Jokers.The images representing the cards are altered in the way they are displayed to get the "WILD" on the deuces and jokers and probably on the OEJs (one eyed Jacks).  But the essence is that there is a "52 card deck" used to play each hand and cards discarded on the initial draw are not eligible for drawing on the redraw, just as would be the case if you were playing with a "hard copy" deck of cards.
