Here's Atari's Black Widow in an FPGA.  this would require a vector to raster conversion circuit.  I think the author released this as free to use.

Gravitar is a ROM swap.  Space Duel could work with some minor tweaks to the source code.

The designer did a slick job implementing the vector state logic.  instead of using proms, they implemented it as a regular state machine :-).
