Great Idea! To keep from running out of cards, I could instead copy card one 1 to
card 52/54 spot (probably 52, I wont use jokers), or I could reshuffle if I got
to 52/54. This way I don't need to recreate the deck or anything, it can just
start off with the last deck, just like a real deck of cards.
I am pretty new to ASM, but I am learning VERY fast by jumping head-first into a
program like my casino (w/ a bar, restaraunt, slot machine, black jack, and 3
card monte as well as being able to start from where you left off). But I still
don't know how to do a lot of things. How would I go about setting this up?
Should I store the deck in an actual list/matrix? If so how do I switch using
ASM? If not how do I switch using ASM? Also, program writeback, I NEED this in my
program, but I can't seem to figure it out. I don't like using shells even though
they often have automatic program writeback as a standard feature. Also if anyone
out there really wants to se this dream become a reality, I am definitely looking
for hints to decrease file size. I do plan on squishing Casino, but it's still
going to be huge. I am avoiding the use of background images where I can (ie only
for the slot machine that really does need it).
