does.. this mean I won't get to test the game now? :_ (

Cool! well now that it's working I'm rather curious why.

Hi David,

Thanks, I'll try those things.  I already sent a new binary to Al with a different method of reading CXP0FB in it - instead of

   lda CXP0FB
   sta SantaTemp

I changed it to

   bit CXP0FB
   bpl NoPFCollision
   lda #$FF
   .byte $2C
NoPFCollision
   lda #0
   sta SantaTemp

So we'll see if that has any effect.  If not, I'll make up a batch of binaries with every different method of reading CXP0FB that is feasible and see what works...

Well, I just heard back from Al and that change (from using LDA to using BIT) worked!

Have to remember this when/if I write a 16K game again...

Thanks,

-bob
