> 1) What is the difference in a masked sprite and an unmasked sprite?
masked sprites have two parts - like
.db %10000001
.db %10000001
.db %10000001
.db %10000001
.db %10000001
.db %10000001
.db %10000001
.db %10000001
and then the mask.. like
.db %00000000
.db %00000000
.db %00000000
.db %00000000
.db %00000000
.db %00000000
.db %00000000
.db %00000000
> 2) I have my sprites made, but how do I put them on the screen?
You just need a sprite routine.. there is one in DuckHunt that's XOR... Dan
Eble made one too, but i think the one in DuckHunt is smaller, of course i
could be wrong..

if I understand you right that your talking about the Mario screen, its
simply using scrolling... use the softscroll routines i ported from
ticalc.org and modify the start/stop location to allow scrolling from
midscreen.
