Is it possible to do 640x480x16? Yes, so long as you have a graphics card
with enough memory (about 1MB should do it) which most cards have.
Is it possible to have 12 objects on screen at once? Should be no problem
for a P133. Those of us in the G'98RGT team are currently in the process of
programming a game in 640x480x16. We plan to have quite a few more objects
than 12 on screen at once. Our minimum spec is any Pentium (although since
there is no Pentium specific code, it should run on any system with enough
video RAM to handle the resolution). What you are suggesting could be done
on a 386 with a good graphics card. A Pentium would hardly feel the
pressure.
BTW, palette allocation is not all that hard. If you have a good art
package, it will tell you how many colours it used for each image. You
should also be able to create a user palette which you can use for each
graphic you make. PSP does all this, but so do several other packages. The
hard bit is keeping each image in sync with the palette...
