Need help with sprites from Desert Demolition for Sega Genesis

[LooneyTunerIan]

This is proving to be quite a bit more difficult than the cannon, and my unfamiliarity with YY-CHR isn't helping much. The bits and pieces being displayed make absolutely no sense to me trying to assemble them.

For anyone wanting to try, here's what I did.

• Save a state of Desert Demolition (The third level is where the sprites are available, it's an easy game so that's no problem)
  
• Open the state in YY-CHR
  
• Set the graphics format to 4BPP MSX/MD/WSC
  
• Pattern really doesn't matter in my opinion, as long as you can see where the catapult tiles are.
  
• Assemble
  

If someone a bit more experienced with the program can take this up, that would be very appreciated.

Sorry dude.

That's ok, you tried your best.

Maybe Nate'll help out.

How about if you can help me with something else I couldn't get to sprite:


I tried to get this teeter-totter sprited, but Wile E. Coyote and the boulder got in the way sadly and I couldn't find a way to get them off.  

Could you maybe help me out with the teeter-totter sprites?
