Ouch...I have a while to go before I understand what Andrew Davie
said. (and that much further before I should try adding it to my
tutorial) It seems you can get a bit done just by assigning a few
name/memory locations at the top, ala "how to build a playfield"...
obviously, as memory needs increase, so do requirements to understand
overlays and when you need to get into paging, and how many pages
there are.
Actually, is the idea of overlays that you can use one 16 bit location
for multiple smaller variables? (1 bit flags, 8 bit small values, etc)
Any doc recomendations? Also, anything that talks about the
ORG syntax, and where and how to stick graphics. (More specific
question: in Nick's "how to draw", the
org $F000
at the top and the
org $FFFC
.word Start
.word Start
at the bottom
