Color hacking question

[Tombor]

Hi again...

 

I'm working on a hack of Berzerk right now and I'm using the Distella/Hex technique and I've gotten the graphics done but I'm having a hard time spotting color hex values (I think that's how you put it).

 

I'm using a TIA colorchart that Andrew Davie posted on his 2600 for Newbies tutorials and it SEEMS that all the colors seem to be marked "#$00." I found what I think is the color of the player character labeled as "#$FF" (that strange pinkish color) but I'm not really sure. Is there an easy way to spot the color hexs? The above seem to be sporadically laid out.

As Thomas pointed out, the lowest bit is unused in color values by Atari hardware (so odd values you can rule out, stick to even values). Otherwise, your best bet is to run the game thru a disassembler and see which values are loaded into the color registers. Not all games group the colors into a table, but I'd guess that most do. So if you want to hunt instead, try looking for a group of even values.
