• 4k Atari VCS Nyantari 2600 by Tjoppen
• Exin: I assume you mean the rainbow tail, which would mean moving the cat/tart right. The problem with that lies with how playfield graphics work.
  ATM I'm using a repeated playfield, which means I'd have to move the thing 4*(4+8) = 48 pixels to the right, landing the thing almost on the right edge of the screen.
  With a reflected playfield I could reduce that to 32.
  However, reflecting the playfield would mean I don't have time to clear the rainbow graphics in PF2 before it's drawn again for the right side, meaning the rainbow colors would bleed into the tart.
  
  TL;DR
  Moving the thing horizontally is not feasible.

• For the platform, name and beepy/scratchy music. But complaining about having "only" 16k doesn't seem fair to us VCS folk who have sqrt() of that to work with :)

• What kind of hypocrite would I be if I didn't thumb this up? :)
  Doesn't sound all that great sampled though - it would probably sound better as normal tracked music.

  phobium: I just realized the lagged drums were a bit of a mistake. Luckily it's not easy to spot :)
  
  Exin: Nah, "Nyan Dash 2600" would just invite haters
  
  killer: Check out version 2, it has the song in the source code. It also has an alternate base line for the second part of the song

  The voice synthesis is a neat hack. The text seems to be what makes it work

• JAC!: I assume you mean LDX ZP,Y - there's no LDA ZP,Y. Also, with four bytes to spare there's no room for another table in RAM.
  
  Reusing color values for ENAx is a good idea for future prods - this time I needed to set HMBL though, meaning the lower bits in that table were free for ENABL.
  
  In retrospect I think it would have been possible do P1's job using the playfield and careful timing, freeing it up for use as a nicer tail.
  
  superplek: Haha :)

  It turns out that drawing Nyan Cat on the VCS is fairly tricky. This thing uses all graphic objects the TIA is able to produce, including the missiles and ball for the tail, left edge and cherries on the tart.
  The cherries were the last thing to go in, since I didn't have enough CPU time to change COLUPF to red and back to blue without messing something up, and still have time to read/write the HMBL/ENABL values.
  
  As for the music, its rapid pace seems to help mask how wonderfully out of tune everything is. I attenuated some of the nastier notes, especially in the bass line. Oh, and the bass and drums have to share the second channel of course :)

  Here's hoping this meme won't be horribly stale in 2012 :)
