Hi guys - I have a new update:

 

 

These are the things I have left:

  • Sound
  • 2 Player Simultaneous bug when player 1 dies (just found this one)
  • Aliens under player poking up
  • Firebirds:
    •     Divebomb player
    •     Shooting player
  • Level Indicator

 

Hoping to finish this before the end of the year.

Thank you!

 

I'm actually currently rewriting the handling of the first level (the 'Firebirds').  I initially had them as all sprites (repeating the DL each line, as there are only 4 enemies in each zone), but that will prove difficult when they go to divebomb the player.

 

From looking at the arcade game more, I have a feeling the 'flock' is all tiles, and when it's time to divebomb the player that tile is blanked out and a sprite replaces it.  It also looks like there are only 8 sprites in that hardware, which makes me lean more toward the 'flock / tile' theory.  It's the 'Galaxian' hardware, so I wonder if the same thing was done with Galaxian itself; the flock doesn't "spread out" like Galaga does once all enemies are in formation.

 

I know Atari/GCC did Galaga as all sprites, but that's a whole different ballgame.

Arcade Galaxian only uses sprites for the divebombing enemies and bullets.

Ah.  Thank you for confirming my suspicions. :D

Holy Crap!

 

My conversion of the firebirds from sprites to tiles worked first time!  For those of you that program, you know how rare that is...  Ok, now for the collision detection...

 

There may be a Galaxian port in the future if this works out... :D

Just need a Phoenix port after that :D
