I have not tested on real hardware yet, so I doubt the starfield issues you saw are fixed, Yurkie, but in the meantime, here's a new build.
Posted a YouTube Video of the WIP here:
-Implemented new final weapons systems - three versions of wide gun and three versions of pulse cannon (still need to make shield a separate powerup and fix the wide gun icon)
-Fixed boss cockpit sprite to be hidden as intended
-added post-boss bonus tally
-Made boss flash white when engines hit using second color table
-made fat character set out of BIOS character set (idea by Sometimes99er)
-made enemy shots flash to call them out more
-changed screen color reset for bombs
-tweaked scoring
