That's pretty cool, and I might move to some of those more sophisticated
techniques, but I found a great stopgap for myself, since right now I have
some RAM to play with:
The basic idea is I use a byte of RAM as a buffer...the first thing
I do at the start of my kernel is to load that buffer into GRP0, then
I do the calculations for the "next" line of the player during the rest
of the visible line, and finally load up the buffer right before the
WSYNC.
This seems like a reasonably extensible trick for my JoustPong
kernel, though eventually I may run out of time doing all the
LDA Player0Buffer
STA GRP0
LDA Player1Buffer
STA GRP1
It's a nice technique because it's easy, no cycle counting
or page aliging (I've been avoiding thinking about pages...
I don't even have a firm grip on what differentiates the ROM
locations from the RAM locations...)
Hell, pretty soon it might get to the point where it's time
to make JoustPong a webpage...(I realized I'm not as far behind
some other homebrew efforts, now that I have a firm, plausible
gameplay in mind and the start of half decent kernel)
...does anyone think I'm going to get into legal problems with
the name JoustPong? (I don't know why I'm worried now...something
about the prospect of making physical software, and selling it
I guess)...or taking the flyer images from the 2600 port?
If it seems too risky, my plan B is to call it "FLAP" (easier
to make a title screen then too! ;-) and to go back to the
"paddle with wing" graphic I first used with the VB version.
